+# Contributing
+
+We follow the [IPython Contributing Guide](https://github.com/ipython/ipython/blob/master/CONTRIBUTING.md).
+
+For development installation instructions, see the [README](README.md#dev-quickstart).
+
+## Managing static files
+
+The notebook relies on static dependencies (which are installed with Bower), its own minified JavaScript, and CSS compiled from LESS.
+
+### Static dependencies
+
+To install the static dependencies, run:
+
+    python setup.py jsdeps
+
+You can also pass a `-f` flag to this command to force Bower to run, if necessary.
+
+### Minified JavaScript
+
+To compile the minified JavaScript, run:
+
+    python setup.py js
+
+You can also run the notebook server without relying on the minified JavaScript by passing the `--NotebookApp.ignore_minified_js=True` flag when launching the notebook.
+
+### Compiling CSS
+
+To compile the CSS from LESS, run:
+
+    python setup.py css
+
+### Git hooks
+
+If you want to automatically update dependencies, recompile the JavaScript, and recompile the CSS after checking out a new commit, you can install post-checkout and post-merge hooks which will do it for you:
+
+    ./git-hooks/install-hooks.sh
+
+See the [git-hooks readme](git-hooks/README.md) for more details.
+
+## Running tests
+
+### JavaScript tests
+
+To run the JavaScript tests, you will need to have PhantomJS and CasperJS installed:
+
+    npm install -g casperjs phantomjs@1.9.18
+
+Then, to run the JavaScript tests:
+
+    python -m notebook.jstest [group]
+
+where `[group]` is an optional argument that is a path relative to `notebook/tests`. For example, to run all tests in `notebook/tests/notebook`:
+
+    python -m notebook.jstest notebook
+
+or to run just `notebook/tests/notebook/deletecell.js`:
+
+    python -m notebook.jstest notebook/deletecell.js
+
+### Python tests
+
+To run Python tests, run:
+
+    nosetests notebook
+
+If you want coverage statistics as well, you can run:
+
+    nosetests --with-coverage --cover-package=notebook notebook

+## About the Jupyter Development Team
+
+The Jupyter Development Team is the set of all contributors to the Jupyter project.
+This includes all of the Jupyter subprojects.
+
+The core team that coordinates development on GitHub can be found here:
+https://github.com/jupyter/.
+
+## Our Copyright Policy
+
+Jupyter uses a shared copyright model. Each contributor maintains copyright
+over their contributions to Jupyter. But, it is important to note that these
+contributions are typically only changes to the repositories. Thus, the Jupyter
+source code, in its entirety is not the copyright of any single person or
+institution.  Instead, it is the collective copyright of the entire Jupyter
+Development Team.  If individual contributors want to maintain a record of what
+changes/contributions they have specific copyright on, they should indicate
+their copyright in the commit message of the change, when they commit the
+change to one of the Jupyter repositories.
+
+With this in mind, the following banner should be used in any source code file
+to indicate the copyright and license terms:

+# Jupyter Notebook
+
+[![Google Group](https://img.shields.io/badge/-Google%20Group-lightgrey.svg)](https://groups.google.com/forum/#!forum/jupyter)
+[![Build Status](https://travis-ci.org/jupyter/notebook.svg?branch=master)](https://travis-ci.org/jupyter/notebook)
+[![Documentation Status](https://readthedocs.org/projects/jupyter-notebook/badge/?version=latest)](http://jupyter-notebook.readthedocs.org/en/latest/?badge=latest)
+
+The Jupyter notebook is a web-based notebook environment for interactive
+computing.
+
+![Jupyter notebook example](docs/resources/running_code_med.png "Jupyter notebook example")
+
+### Jupyter notebook, the language-agnostic evolution of IPython notebook
+Jupyter notebook is the language-agnostic HTML notebook application for
+Project Jupyter. In 2015, Jupyter notebook was released as part of
+The Big Split™ of the IPython codebase. IPython 3 was the last major monolithic
+release containing both language-agnostic code, such as the *IPython notebook*,
+and language specific code, such as the *IPython kernel for Python*. As
+computing spans many languages, Project Jupyter will continue to develop the
+language-agnostic **Jupyter notebook** in this repo and with the help of the
+community develop language specific kernels which are found in their own
+discrete repos.
+[[The Big Split™ announcement](https://blog.jupyter.org/2015/04/15/the-big-split/)]
+[[Jupyter Ascending blog post](http://blog.jupyter.org/2015/08/12/first-release-of-jupyter/)]
+
+## Installation
+You can find the installation documentation for the
+[Jupyter platform, on ReadTheDocs](http://jupyter.readthedocs.org/en/latest/install.html).
+The documentation for advanced usage of Jupyter notebook can be found
+[here](http://jupyter-notebook.readthedocs.org/en/latest).
+
+For a local installation, make sure you have
+[pip installed](https://pip.readthedocs.org/en/stable/installing/) and run:
+
+    $ pip install notebook
+
+## Usage - Running Jupyter notebook
+
+### Running in a local installation
+
+Launch with:
+
+    $ jupyter notebook
+
+### Running in a Docker container
+
+If you are using **Linux** and have a
+[Docker daemon running](https://docs.docker.com/installation/),
+e.g. reachable on `localhost`, start a container with:
+
+    $ docker run --rm -it -p 8888:8888 -v "$(pwd):/notebooks" jupyter/notebook
+
+In your browser, open the URL `http://localhost:8888/`.
+All notebooks from your session will be saved in the current directory.
+
+On other platforms, such as **Windows and OS X**, that use
+[`docker-machine`](https://docs.docker.com/machine/install-machine/) with `docker`, a container can be started using
+`docker-machine`. In the browser, open the URL `http://ip:8888/` where `ip` is
+the IP address returned from the command [`docker-machine ip <MACHINE>`](https://docs.docker.com/machine/reference/ip/):
+
+    $ docker-machine ip <MACHINE>
+
+For example,
+
+    $ docker-machine ip myjupytermachine
+    192.168.99.104
+
+In browser, open `http://192.168.99.104:8888`.
+
+NOTE: With the deprecated `boot2docker`, use the command `boot2docker ip` to
+determine the URL.
+
+## Development Installation Quickstart
+Detailed [Developer Documentation](http://jupyter-notebook.readthedocs.org/en/latest)
+is available on ReadTheDocs.
+
+* Ensure that you have node/npm installed (e.g. `brew install node` on OS X)
+* Clone this repo and `cd` into it
+* `pip install --pre -e .`
+
+NOTE: For **Debian/Ubuntu** systems, if you're installing the system node you
+need to use the 'nodejs-legacy' package and not the 'node' package.
+
+For more detailed development install instructions (e.g. recompiling javascript
+and css, running tests), see the
+[Developer Documentation](http://jupyter-notebook.readthedocs.org/en/latest)
+on ReadTheDocs and the [contributing guide](CONTRIBUTING.md).
+
+### Ubuntu Trusty
+
+```
+sudo apt-get install nodejs-legacy npm python-virtualenv python-dev
+# ensure setuptools/pip are up-to-date
+pip install --upgrade setuptools pip
+git clone https://github.com/jupyter/notebook.git
+cd notebook
+pip install --pre -e .
+jupyter notebook
+```
+
+### FreeBSD
+
+```
+cd /usr/ports/www/npm
+sudo make install    # (Be sure to select the "NODE" option)
+cd /usr/ports/devel/py-pip
+sudo make install
+cd /usr/ports/devel/py-virtualenv
+sudo make install
+cd /usr/ports/shells/bash
+sudo make install
+mkdir -p ~/.virtualenvs
+python2.7 -m virtualenv ~/.virtualenvs/notebook
+bash
+source ~/.virtualenvs/notebook/bin/activate
+pip install --upgrade setuptools pip pycurl
+git clone https://github.com/jupyter/notebook.git
+cd notebook
+pip install -r requirements.txt -e .
+jupyter notebook
+```

+- Send keepalive messages for web terminals
+- Fix bugs in the notebook tour
+
+UI changes:
+
+- Moved the cell toolbar selector into the *View* menu. Added a button that triggers a "hint" animation to the main toolbar so users can find the new location. (Click here to see a `screencast <https://cloud.githubusercontent.com/assets/335567/10711889/59665a5a-7a3e-11e5-970f-86b89592880c.gif>`__ )
+
+    .. image:: /_static/images/cell-toolbar-41.png
+
+- Added *Restart & Run All* to the *Kernel* menu. Users can also bind it to a keyboard shortcut on action ``restart-kernel-and-run-all-cells``.
+- Added multiple-cell selection. Users press ``Shift-Up/Down`` or ``Shift-K/J`` to extend selection in command mode. Various actions such as cut/copy/paste, execute, and cell type conversions apply to all selected cells.
+
+  .. image:: /_static/images/multi-select-41.png
+
+- Added a command palette for executing Jupyter actions by name. Users press ``Cmd/Ctrl-Shift-P`` or click the new command palette icon on the toolbar.
+
+  .. image:: /_static/images/command-palette-41.png
+
+- Added a *Find and Replace* dialog to the *Edit* menu. Users can also press ``F`` in command mode to show the dialog.
+
+  .. image:: /_static/images/find-replace-41.png
+
+Other improvements:
+
+- Custom KernelManager methods can be Tornado coroutines, allowing async operations.
+- Make clearing output optional when rewriting input with ``set_next_input(replace=True)``.
+- Added support for TLS client authentication via ``--NotebookApp.client-ca``.
+- Added tags to ``jupyter/notebook`` releases on DockerHub. ``latest`` continues to track the master branch.

+
+Installing Javascript machinery
+===============================
+
+Running the Notebook from the source code on GitHub requires some JavaScript
+tools to build/minify the CSS and JavaScript components. We do these steps when
+making releases, so there's no need for these tools when installing released
+versions of the Notebook.
+
+First, install `Node.js <https://nodejs.org/>`_. The installers on the
+Node.js website also include Node's package manager, *npm*. Alternatively,
+install both of these from your package manager. For example, on Ubuntu or Debian::
+
+    sudo apt-get install nodejs-legacy npm
+
+You can then build the JavaScript and CSS by running::
+
+    python setup.py css js
+
+This will automatically fetch the remaining dependencies (bower, less) and
+install them in a subdirectory.
+
+For quick iteration on the Notebook's JavaScript you can deactivate the use of
+the bundled and minified JavaScript by using the option
+``--NotebookApp.ignore_minified_js=True``.  This might though highly increase the
+number of requests that the browser make to the server, but can allow to test
+JavaScript file modification without going through the compilation step that
+can take up to 30 sec.
+
+
+Making a notebook release
+-------------------------
+
+Make sure you have followed the step above and have all the tools to generate
+the minified JavaScript and CSS files. 
+
+Make sure the repository is clean of any file that could be problematic. 
+You can remove all non-tracked files with:
+
+.. code::
+
+    $ git clean -xfdi
+
+This would ask you for confirmation before removing all untracked files. Make
+sure the ``dist/`` folder is clean and avoid stale build from
+previous attempts.
+
+1. Update version number in ``notebook/_version.py``.
+
+2. Run ``$ python setup.py jsversion``. It will modify (at least)
+``notebook/static/base/js/namespace.js`` to make the notebook version available
+from within JavaScript.
+
+3 . Commit and tag the release with the current version number:
+
+.. code::
+
+    git commit -am "release $VERSION"
+    git tag $VERSION
+
+
+4. You are now ready to build the ``sdist`` and ``wheel``:
+
+.. code::
+
+    $ python setup.py sdist --formats=zip,gztar
+    $ python setup.py bdist_wheel
+
+
+5. You can now test the ``wheel`` and the ``sdist`` locally before uploading to PyPI.
+Make sure to use `twine <https://github.com/pypa/twine>`_ to upload the archives over SSL.
+
+.. code::
+
+    $ twine upload dist/*
+
+6. If all went well, change the ``notebook/_version.py`` back adding the ``.dev`` suffix.
+
+7. Push directly on master, not forgetting to push ``--tags``.

+
+Connecting to an existing IPython kernel using the Qt Console
+=============================================================
+
+The Frontend/Kernel Model
+-------------------------
+
+The traditional IPython (``ipython``) consists of a single process that
+combines a terminal based UI with the process that runs the users code.
+
+While this traditional application still exists, the modern Jupyter
+consists of two processes:
+
+-  Kernel: this is the process that runs the users code.
+-  Frontend: this is the process that provides the user interface where
+   the user types code and sees results.
+
+Jupyter currently has 3 frontends:
+
+-  Terminal Console (``ipython console``)
+-  Qt Console (``ipython qtconsole``)
+-  Notebook (``ipython notebook``)
+
+The Kernel and Frontend communicate over a ZeroMQ/JSON based messaging
+protocol, which allows multiple Frontends (even of different types) to
+communicate with a single Kernel. This opens the door for all sorts of
+interesting things, such as connecting a Console or Qt Console to a
+Notebook's Kernel. For example, you may want to connect a Qt console to
+your Notebook's Kernel and use it as a help browser, calling ``??`` on
+objects in the Qt console (whose pager is more flexible than the one in
+the notebook).
+
+This Notebook describes how you would connect another Frontend to a
+Kernel that is associated with a Notebook.
+
+Manual connection
+-----------------
+
+To connect another Frontend to a Kernel manually, you first need to find
+out the connection information for the Kernel using the
+``%connect_info`` magic:
+
+.. code:: python
+
+    %connect_info
+
+You can see that this magic displays everything you need to connect to
+this Notebook's Kernel.
+
+Automatic connection using a new Qt Console
+-------------------------------------------
+
+You can also start a new Qt Console connected to your current Kernel by
+using the ``%qtconsole`` magic. This will detect the necessary
+connection information and start the Qt Console for you automatically.
+
+.. code:: python
+
+    a = 10
+
+.. code:: python
+
+    %qtconsole

+
+Keyboard Shortcut Customization
+===============================
+
+Starting with IPython 2.0 keyboard shortcuts in command and edit mode
+are fully customizable. These customizations are made using the Jupyter
+JavaScript API. Here is an example that makes the ``r`` key available
+for running a cell:
+
+.. code:: python
+
+    %%javascript
+    
+    Jupyter.keyboard_manager.command_shortcuts.add_shortcut('r', {
+        help : 'run cell',
+        help_index : 'zz',
+        handler : function (event) {
+            IPython.notebook.execute_cell();
+            return false;
+        }}
+    );
+
+"By default the keypress ``r``, while in command mode, changes the type
+of the selected cell to ``raw``. This shortcut is overridden by the code
+in the previous cell, and thus the action no longer be available via the
+keypress ``r``."
+
+There are a couple of points to mention about this API:
+
+-  The ``help_index`` field is used to sort the shortcuts in the
+   Keyboard Shortcuts help dialog. It defaults to ``zz``.
+-  When a handler returns ``false`` it indicates that the event should
+   stop propagating and the default action should not be performed. For
+   further details about the ``event`` object or event handling, see the
+   jQuery docs.
+-  If you don't need a ``help`` or ``help_index`` field, you can simply
+   pass a function as the second argument to ``add_shortcut``.
+
+.. code:: python
+
+    %%javascript
+    
+    Jupyter.keyboard_manager.command_shortcuts.add_shortcut('r', function (event) {
+        IPython.notebook.execute_cell();
+        return false;
+    });
+
+Likewise, to remove a shortcut, use ``remove_shortcut``:
+
+.. code:: python
+
+    %%javascript
+    
+    Jupyter.keyboard_manager.command_shortcuts.remove_shortcut('r');
+
+If you want your keyboard shortcuts to be active for all of your
+notebooks, put the above API calls into your ``custom.js`` file.
+
+Of course we provide name for majority of existing action so that you do
+not have to re-write everything, here is for example how to bind ``r``
+back to it's initial behavior:
+
+.. code:: python
+
+    %%javascript
+    
+    Jupyter.keyboard_manager.command_shortcuts.add_shortcut('r', 'jupyter-notebook:change-cell-to-raw');

+
+Distributing Jupyter Extensions as Python Packages
+==================================================
+
+Overview
+--------
+
+How can the notebook be extended?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Jupyter Notebook client and server application are both deeply
+customizable. Their behavior can be extended by creating, respectively:
+
+-  nbextension: a notebook extension
+
+   -  a single JS file, or directory of JavaScript, Cascading
+      StyleSheets, etc. that contain at minimum a JavaScript module
+      packaged as an `AMD
+      modules <https://en.wikipedia.org/wiki/Asynchronous_module_definition>`__
+      that exports a function ``load_ipython_extension``
+
+-  server extension: an importable Python module
+
+   -  that implements ``load_jupyter_server_extension``
+
+Why create a Python package for Jupyter extensions?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Since it is rare to have a server extension that does not have any
+frontend components (an nbextension), for convenience and consistency,
+all these client and server extensions with their assets can be packaged
+and versioned together as a Python package with a few simple commands.
+This makes installing the package of extensions easier and less
+error-prone for the user.
+
+Installation of Jupyter Extensions
+----------------------------------
+
+Install a Python package containing Jupyter Extensions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are several ways that you may get a Python package containing
+Jupyter Extensions. Commonly, you will use a package manager for your
+system:
+
+.. code:: shell
+
+    pip install helpful_package
+    # or
+    conda install helpful_package
+    # or
+    apt-get install helpful_package
+
+    # where 'helpful_package' is a Python package containing one or more Jupyter Extensions
+
+Enable a Server Extension
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The simplest case would be to enable a server extension which has no
+frontend components.
+
+A ``pip`` user that wants their configuration stored in their home
+directory would type the following command:
+
+.. code:: shell
+
+    jupyter serverextension enable --py helpful_package
+
+Alternatively, a ``virtualenv`` or ``conda`` user can pass
+``--sys-prefix`` which keeps their environment isolated and
+reproducible. For example:
+
+.. code:: shell
+
+    # Make sure that your virtualenv or conda environment is activated
+    [source] activate my-environment
+
+    jupyter serverextension enable --py helpful_package --sys-prefix
+
+Install the nbextension assets
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a package also has an nbextension with frontend assets that must be
+available (but not neccessarily enabled by default), install these
+assets with the following command:
+
+.. code:: shell
+
+    jupyter nbextension install --py helpful_package # or --sys-prefix if using virtualenv or conda
+
+Enable nbextension assets
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a package has assets that should be loaded every time a Jupyter app
+(e.g. lab, notebook, dashboard, terminal) is loaded in the browser, the
+following command can be used to enable the nbextension:
+
+.. code:: shell
+
+    jupyter nbextension enable --py helpful_package # or --sys-prefix if using virtualenv or conda
+
+Did it work? Check by listing Jupyter Extensions.
+-------------------------------------------------
+
+After running one or more extension installation steps, you can list
+what is presently known about nbextensions or server extension. The
+following commands will list which extensions are available, whether
+they are enabled, and other extension details:
+
+.. code:: shell
+
+    jupyter nbextension list
+    jupyter serverextension list
+
+Additional resources on creating and distributing packages
+----------------------------------------------------------
+
+    Of course, in addition to the files listed, there are number of
+    other files one needs to build a proper package. Here are some good
+    resources: - `The Hitchhiker's Guide to
+    Packaging <http://the-hitchhikers-guide-to-packaging.readthedocs.org/en/latest/quickstart.html>`__
+    - `Repository Structure and
+    Python <http://www.kennethreitz.org/essays/repository-structure-and-python>`__
+    by Kenneth Reitz
+
+    How you distribute them, too, is important: - `Packaging and
+    Distributing
+    Projects <http://python-packaging-user-guide.readthedocs.org/en/latest/distributing/>`__
+    - `conda: Building
+    packages <http://conda.pydata.org/docs/building/build.html>`__
+
+    Here are some tools to get you started: -
+    `generator-nbextension <https://github.com/Anaconda-Server/generator-nbextension>`__
+
+Example - Server extension
+--------------------------
+
+Creating a Python package with a server extension
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here is an example of a python module which contains a server extension
+directly on itself. It has this directory structure:
+
+::
+
+    - setup.py
+    - MANIFEST.in
+    - my_module/
+      - __init__.py
+
+Defining the server extension
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This example shows that the server extension and its
+``load_jupyter_server_extension`` function are defined in the
+``__init__.py`` file.
+
+``my_module/__init__.py``
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code:: python
+
+    def _jupyter_server_extension_paths():
+        return [{
+            "module": "my_module"
+        }]
+
+
+    def load_jupyter_server_extension(nbapp):
+        nbapp.log.info("my module enabled!")
+
+Install and enable the server extension
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Which a user can install with:
+
+::
+
+    jupyter serverextension enable --py my_module [--sys-prefix]
+
+Example - Server extension and nbextension
+------------------------------------------
+
+Creating a Python package with a server extension and nbextension
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here is another server extension, with a front-end module. It assumes
+this directory structure:
+
+::
+
+    - setup.py
+    - MANIFEST.in
+    - my_fancy_module/
+      - __init__.py
+      - static/
+        index.js
+
+Defining the server extension and nbextension
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This example again shows that the server extension and its
+``load_jupyter_server_extension`` function are defined in the
+``__init__.py`` file. This time, there is also a function
+``_jupyter_nbextension_path`` for the nbextension.
+
+``my_fancy_module/__init__.py``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code:: python
+
+    def _jupyter_server_extension_paths():
+        return [{
+            "module": "my_fancy_module"
+        }]
+
+    # Jupyter Extension points
+    def _jupyter_nbextension_paths():
+        return [dict(
+            section="notebook",
+            # the path is relative to the `my_fancy_module` directory
+            src="static",
+            # directory in the `nbextension/` namespace
+            dest="my_fancy_module",
+            # _also_ in the `nbextension/` namespace
+            require="my_fancy_module/index")]
+
+    def load_jupyter_server_extension(nbapp):
+        nbapp.log.info("my module enabled!")
+
+Install and enable the server extension and nbextension
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The user can install and enable the extensions with the following set of
+commands:
+
+::
+
+    jupyter nbextension install --py my_fancy_module [--sys-prefix|--user]
+    jupyter nbextension enable --py my_fancy_module [--sys-prefix|--system]
+    jupyter serverextension enable --py my_fancy_module [--sys-prefix|--system]

+
+Importing Jupyter Notebooks as Modules
+======================================
+
+It is a common problem that people want to import code from Jupyter
+Notebooks. This is made difficult by the fact that Notebooks are not
+plain Python files, and thus cannot be imported by the regular Python
+machinery.
+
+Fortunately, Python provides some fairly sophisticated
+`hooks <http://www.python.org/dev/peps/pep-0302/>`__ into the import
+machinery, so we can actually make Jupyter notebooks importable without
+much difficulty, and only using public APIs.
+
+.. code:: python
+
+    import io, os, sys, types
+
+.. code:: python
+
+    from IPython import get_ipython
+    from IPython.nbformat import current
+    from IPython.core.interactiveshell import InteractiveShell
+
+Import hooks typically take the form of two objects:
+
+1. a Module **Loader**, which takes a module name (e.g.
+   ``'IPython.display'``), and returns a Module
+2. a Module **Finder**, which figures out whether a module might exist,
+   and tells Python what **Loader** to use
+
+.. code:: python
+
+    def find_notebook(fullname, path=None):
+        """find a notebook, given its fully qualified name and an optional path
+        
+        This turns "foo.bar" into "foo/bar.ipynb"
+        and tries turning "Foo_Bar" into "Foo Bar" if Foo_Bar
+        does not exist.
+        """
+        name = fullname.rsplit('.', 1)[-1]
+        if not path:
+            path = ['']
+        for d in path:
+            nb_path = os.path.join(d, name + ".ipynb")
+            if os.path.isfile(nb_path):
+                return nb_path
+            # let import Notebook_Name find "Notebook Name.ipynb"
+            nb_path = nb_path.replace("_", " ")
+            if os.path.isfile(nb_path):
+                return nb_path
+                
+
+Notebook Loader
+---------------
+
+Here we have our Notebook Loader. It's actually quite simple - once we
+figure out the filename of the module, all it does is:
+
+1. load the notebook document into memory
+2. create an empty Module
+3. execute every cell in the Module namespace
+
+Since IPython cells can have extended syntax, the IPython transform is
+applied to turn each of these cells into their pure-Python counterparts
+before executing them. If all of your notebook cells are pure-Python,
+this step is unnecessary.
+
+.. code:: python
+
+    class NotebookLoader(object):
+        """Module Loader for Jupyter Notebooks"""
+        def __init__(self, path=None):
+            self.shell = InteractiveShell.instance()
+            self.path = path
+        
+        def load_module(self, fullname):
+            """import a notebook as a module"""
+            path = find_notebook(fullname, self.path)
+            
+            print ("importing Jupyter notebook from %s" % path)
+                                           
+            # load the notebook object
+            with io.open(path, 'r', encoding='utf-8') as f:
+                nb = current.read(f, 'json')
+            
+            
+            # create the module and add it to sys.modules
+            # if name in sys.modules:
+            #    return sys.modules[name]
+            mod = types.ModuleType(fullname)
+            mod.__file__ = path
+            mod.__loader__ = self
+            mod.__dict__['get_ipython'] = get_ipython
+            sys.modules[fullname] = mod
+            
+            # extra work to ensure that magics that would affect the user_ns
+            # actually affect the notebook module's ns
+            save_user_ns = self.shell.user_ns
+            self.shell.user_ns = mod.__dict__
+            
+            try:
+              for cell in nb.worksheets[0].cells:
+                if cell.cell_type == 'code' and cell.language == 'python':
+                    # transform the input to executable Python
+                    code = self.shell.input_transformer_manager.transform_cell(cell.input)
+                    # run the code in themodule
+                    exec(code, mod.__dict__)
+            finally:
+                self.shell.user_ns = save_user_ns
+            return mod
+
+
+The Module Finder
+-----------------
+
+The finder is a simple object that tells you whether a name can be
+imported, and returns the appropriate loader. All this one does is
+check, when you do:
+
+.. code:: python
+
+    import mynotebook
+
+it checks whether ``mynotebook.ipynb`` exists. If a notebook is found,
+then it returns a NotebookLoader.
+
+Any extra logic is just for resolving paths within packages.
+
+.. code:: python
+
+    class NotebookFinder(object):
+        """Module finder that locates Jupyter Notebooks"""
+        def __init__(self):
+            self.loaders = {}
+        
+        def find_module(self, fullname, path=None):
+            nb_path = find_notebook(fullname, path)
+            if not nb_path:
+                return
+            
+            key = path
+            if path:
+                # lists aren't hashable
+                key = os.path.sep.join(path)
+            
+            if key not in self.loaders:
+                self.loaders[key] = NotebookLoader(path)
+            return self.loaders[key]
+
+
+Register the hook
+-----------------
+
+Now we register the ``NotebookFinder`` with ``sys.meta_path``
+
+.. code:: python
+
+    sys.meta_path.append(NotebookFinder())
+
+After this point, my notebooks should be importable.
+
+Let's look at what we have in the CWD:
+
+.. code:: python
+
+    ls nbpackage
+
+So I should be able to ``import nbimp.mynotebook``.
+
+Aside: displaying notebooks
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here is some simple code to display the contents of a notebook with
+syntax highlighting, etc.
+
+.. code:: python
+
+    from pygments import highlight
+    from pygments.lexers import PythonLexer
+    from pygments.formatters import HtmlFormatter
+    
+    from IPython.display import display, HTML
+    
+    formatter = HtmlFormatter()
+    lexer = PythonLexer()
+    
+    # publish the CSS for pygments highlighting
+    display(HTML("""
+    <style type='text/css'>
+    %s
+    </style>
+    """ % formatter.get_style_defs()
+    ))
+
+.. code:: python
+
+    def show_notebook(fname):
+        """display a short summary of the cells of a notebook"""
+        with io.open(fname, 'r', encoding='utf-8') as f:
+            nb = current.read(f, 'json')
+        html = []
+        for cell in nb.worksheets[0].cells:
+            html.append("<h4>%s cell</h4>" % cell.cell_type)
+            if cell.cell_type == 'code':
+                html.append(highlight(cell.input, lexer, formatter))
+            else:
+                html.append("<pre>%s</pre>" % cell.source)
+        display(HTML('\n'.join(html)))
+    
+    show_notebook(os.path.join("nbpackage", "mynotebook.ipynb"))
+
+So my notebook has a heading cell and some code cells, one of which
+contains some IPython syntax.
+
+Let's see what happens when we import it
+
+.. code:: python
+
+    from nbpackage import mynotebook
+
+Hooray, it imported! Does it work?
+
+.. code:: python
+
+    mynotebook.foo()
+
+Hooray again!
+
+Even the function that contains IPython syntax works:
+
+.. code:: python
+
+    mynotebook.has_ip_syntax()
+
+Notebooks in packages
+---------------------
+
+We also have a notebook inside the ``nb`` package, so let's make sure
+that works as well.
+
+.. code:: python
+
+    ls nbpackage/nbs
+
+Note that the ``__init__.py`` is necessary for ``nb`` to be considered a
+package, just like usual.
+
+.. code:: python
+
+    show_notebook(os.path.join("nbpackage", "nbs", "other.ipynb"))
+
+.. code:: python
+
+    from nbpackage.nbs import other
+    other.bar(5)
+
+So now we have importable notebooks, from both the local directory and
+inside packages.
+
+I can even put a notebook inside IPython, to further demonstrate that
+this is working properly:
+
+.. code:: python
+
+    import shutil
+    from IPython.utils.path import get_ipython_package_dir
+    
+    utils = os.path.join(get_ipython_package_dir(), 'utils')
+    shutil.copy(os.path.join("nbpackage", "mynotebook.ipynb"),
+                os.path.join(utils, "inside_ipython.ipynb")
+    )
+
+and import the notebook from ``IPython.utils``
+
+.. code:: python
+
+    from IPython.utils import inside_ipython
+    inside_ipython.whatsmyname()
+
+This approach can even import functions and classes that are defined in
+a notebook using the ``%%cython`` magic.

+
+Embracing web standards
+=======================
+
+One of the main reasons why we developed the current notebook web
+application was to embrace the web technology.
+
+By being a pure web application using HTML, Javascript, and CSS, the
+Notebook can get all the web technology improvement for free. Thus, as
+browser support for different media extend, the notebook web app should
+be able to be compatible without modification.
+
+This is also true with performance of the User Interface as the speed of
+Javascript VM increases.
+
+The other advantage of using only web technology is that the code of the
+interface is fully accessible to the end user and is modifiable live.
+Even if this task is not always easy, we strive to keep our code as
+accessible and reusable as possible. This should allow us - with minimum
+effort - development of small extensions that customize the behavior of
+the web interface.
+
+Tampering with the Notebook application
+---------------------------------------
+
+The first tool that is available to you and that you should be aware of
+are browser "developers tool". The exact naming can change across
+browser and might require the installation of extensions. But basically
+they can allow you to inspect/modify the DOM, and interact with the
+javascript code that runs the frontend.
+
+-  In Chrome and Safari, Developer tools are in the menu
+   ``View > Developer > Javascript Console``
+-  In Firefox you might need to install
+   `Firebug <http://getfirebug.com/>`__
+
+Those will be your best friends to debug and try different approaches
+for your extensions.
+
+Injecting JS
+~~~~~~~~~~~~
+
+Using magics
+^^^^^^^^^^^^
+
+The above tools can be tedious for editing edit long JavaScript files.
+Therefore we provide the ``%%javascript`` magic. This allows you to
+quickly inject JavaScript into the notebook. Still the javascript
+injected this way will not survive reloading. Hence, it is a good tool
+for testing an refining a script.
+
+You might see here and there people modifying css and injecting js into
+the notebook by reading file(s) and publishing them into the notebook.
+Not only does this often break the flow of the notebook and make the
+re-execution of the notebook broken, but it also means that you need to
+execute those cells in the entire notebook every time you need to update
+the code.
+
+This can still be useful in some cases, like the ``%autosave`` magic
+that allows you to control the time between each save. But this can be
+replaced by a JavaScript dropdown menu to select the save interval.
+
+.. code:: python
+
+    ## you can inspect the autosave code to see what it does.
+    %autosave??
+
+custom.js
+^^^^^^^^^
+
+To inject Javascript we provide an entry point: ``custom.js`` that
+allows the user to execute and load other resources into the notebook.
+Javascript code in ``custom.js`` will be executed when the notebook app
+starts and can then be used to customize almost anything in the UI and
+in the behavior of the notebook.
+
+``custom.js`` can be found in the Jupyter dir. You can share your
+custom.js with others.
+
+Back to theory
+''''''''''''''
+
+.. code:: python
+
+    from jupyter_core.paths import jupyter_config_dir
+    jupyter_dir = jupyter_config_dir()
+    jupyter_dir
+
+and custom js is in
+
+.. code:: python
+
+    import os.path
+    custom_js_path = os.path.join(jupyter_dir, 'custom', 'custom.js')
+
+.. code:: python
+
+    #  my custom js
+    if os.path.isfile(custom_js_path):
+        with open(custom_js_path) as f:
+            print(f.read())
+    else:
+        print("You don't have a custom.js file")  
+
+Note that ``custom.js`` is meant to be modified by user. When writing a
+script, you can define it in a separate file and add a line of
+configuration into ``custom.js`` that will fetch and execute the file.
+
+**Warning** : even if modification of ``custom.js`` takes effect
+immediately after browser refresh (except if browser cache is
+aggressive), *creating* a file in ``static/`` directory needs a **server
+restart**.
+
+Exercise :
+----------
+
+-  Create a ``custom.js`` in the right location with the following
+   content:
+
+   .. code:: javascript
+
+       alert("hello world from custom.js")
+
+-  Restart your server and open any notebook.
+-  Be greeted by custom.js
+
+Have a look at `default
+custom.js <https://github.com/jupyter/notebook/blob/4.0.x/notebook/static/custom/custom.js>`__,
+to see it's content and for more explanation.
+
+For the quick ones :
+~~~~~~~~~~~~~~~~~~~~
+
+We've seen above that you can change the autosave rate by using a magic.
+This is typically something I don't want to type every time, and that I
+don't like to embed into my workflow and documents. (readers don't care
+what my autosave time is). Let's build an extension that allows us to do
+it.
+
+Create a dropdown element in the toolbar (DOM
+``Jupyter.toolbar.element``), you will need
+
+-  ``Jupyter.notebook.set_autosave_interval(miliseconds)``
+-  know that 1 min = 60 sec, and 1 sec = 1000 ms
+
+.. code:: javascript
+
+
+    var label = jQuery('<label/>').text('AutoScroll Limit:');
+    var select = jQuery('<select/>')
+         //.append(jQuery('<option/>').attr('value', '2').text('2min (default)'))
+         .append(jQuery('<option/>').attr('value', undefined).text('disabled'))
+
+         // TODO:
+         //the_toolbar_element.append(label)
+         //the_toolbar_element.append(select);
+         
+    select.change(function() {
+         var val = jQuery(this).val() // val will be the value in [2]
+         // TODO
+         // this will be called when dropdown changes
+
+    });
+
+    var time_m = [1,5,10,15,30];
+    for (var i=0; i < time_m.length; i++) {
+         var ts = time_m[i];
+                                              //[2]   ____ this will be `val` on [1]  
+                                              //     | 
+                                              //     v 
+         select.append($('<option/>').attr('value', ts).text(thr+'min'));
+         // this will fill up the dropdown `select` with
+         // 1 min
+         // 5 min
+         // 10 min
+         // 10 min
+         // ...
+    }
+
+A non-interactive example first
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+I like my cython to be nicely highlighted
+
+.. code:: javascript
+
+    Jupyter.config.cell_magic_highlight['magic_text/x-cython'] = {}
+    Jupyter.config.cell_magic_highlight['magic_text/x-cython'].reg = [/^%%cython/]
+
+``text/x-cython`` is the name of CodeMirror mode name, ``magic_`` prefix
+will just patch the mode so that the first line that contains a magic
+does not screw up the highlighting. ``reg``\ is a list or regular
+expression that will trigger the change of mode.
+
+Get more documentation
+^^^^^^^^^^^^^^^^^^^^^^
+
+Sadly, you will have to read the js source file (but there are lots of
+comments) and/or build the JavaScript documentation using yuidoc. If you
+have ``node`` and ``yui-doc`` installed:
+
+.. code:: bash
+
+    $ cd ~/jupyter/notebook/notebook/static/notebook/js/
+    $ yuidoc . --server
+    warn: (yuidoc): Failed to extract port, setting to the default :3000
+    info: (yuidoc): Starting YUIDoc@0.3.45 using YUI@3.9.1 with NodeJS@0.10.15
+    info: (yuidoc): Scanning for yuidoc.json file.
+    info: (yuidoc): Starting YUIDoc with the following options:
+    info: (yuidoc):
+    { port: 3000,
+      nocode: false,
+      paths: [ '.' ],
+      server: true,
+      outdir: './out' }
+    info: (yuidoc): Scanning for yuidoc.json file.
+    info: (server): Starting server: http://127.0.0.1:3000
+
+and browse http://127.0.0.1:3000 to get documentation
+
+Some convenience methods
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+By browsing the documentation you will see that we have some convenience
+methods that allows us to avoid re-inventing the UI every time :
+
+.. code:: javascript
+
+    Jupyter.toolbar.add_buttons_group([
+            {
+                 'label'   : 'run qtconsole',
+                 'icon'    : 'icon-terminal', // select your icon from 
+                                              // http://fortawesome.github.io/Font-Awesome/icons/
+                 'callback': function(){Jupyter.notebook.kernel.execute('%qtconsole')}
+            }
+            // add more button here if needed.
+            ]);
+
+with a `lot of
+icons <http://fortawesome.github.io/Font-Awesome/icons/>`__ you can
+select from.
+
+Cell Metadata
+-------------
+
+The most requested feature is generally to be able to distinguish an
+individual cell in the notebook, or run a specific action with them. To
+do so, you can either use ``Jupyter.notebook.get_selected_cell()``, or
+rely on ``CellToolbar``. This allows you to register a set of actions
+and graphical elements that will be attached to individual cells.
+
+Cell Toolbar
+~~~~~~~~~~~~
+
+You can see some example of what can be done by toggling the
+``Cell Toolbar`` selector in the toolbar on top of the notebook. It
+provides two default ``presets`` that are ``Default`` and ``slideshow``.
+Default allows the user to edit the metadata attached to each cell
+manually.
+
+First we define a function that takes at first parameter an element on
+the DOM in which to inject UI element. The second element is the cell
+this element wis registered with. Then we will need to register that
+function and give it a name.
+
+Register a callback
+^^^^^^^^^^^^^^^^^^^
+
+.. code:: python
+
+    %%javascript
+    var CellToolbar = Jupyter.CellToolbar
+    var toggle =  function(div, cell) {
+         var button_container = $(div)
+    
+         // let's create a button that shows the current value of the metadata
+         var button = $('<button/>').addClass('btn btn-mini').text(String(cell.metadata.foo));
+    
+         // On click, change the metadata value and update the button label
+         button.click(function(){
+                     var v = cell.metadata.foo;
+                     cell.metadata.foo = !v;
+                     button.text(String(!v));
+                 })
+    
+         // add the button to the DOM div.
+         button_container.append(button);
+    }
+    
+     // now we register the callback under the name foo to give the
+     // user the ability to use it later
+     CellToolbar.register_callback('tuto.foo', toggle);
+
+Registering a preset
+^^^^^^^^^^^^^^^^^^^^
+
+This function can now be part of many ``preset`` of the CellToolBar.
+
+.. code:: python
+
+    %%javascript
+    Jupyter.CellToolbar.register_preset('Tutorial 1',['tuto.foo','default.rawedit'])
+    Jupyter.CellToolbar.register_preset('Tutorial 2',['slideshow.select','tuto.foo'])
+
+You should now have access to two presets :
+
+-  Tutorial 1
+-  Tutorial 2
+
+And check that the buttons you defined share state when you toggle
+preset. Also check that the metadata of the cell is modified when you
+click the button, and that when saved on reloaded the metadata is still
+available.
+
+Exercise:
+^^^^^^^^^
+
+Try to wrap the all code in a file, put this file in
+``{jupyter_dir}/custom/<a-name>.js``, and add
+
+::
+
+    require(['custom/<a-name>']);
+
+in ``custom.js`` to have this script automatically loaded in all your
+notebooks.
+
+``require`` is provided by a `javascript
+library <http://requirejs.org/>`__ that allow you to express dependency.
+For simple extension like the previous one we directly mute the global
+namespace, but for more complex extension you could pass a callback to
+``require([...], <callback>)`` call, to allow the user to pass
+configuration information to your plugin.
+
+In Python lang,
+
+.. code:: javascript
+
+    require(['a/b', 'c/d'], function( e, f){
+        e.something()
+        f.something()
+    })
+
+could be read as
+
+.. code:: python
+
+    import a.b as e
+    import c.d as f
+    e.something()
+    f.something()
+
+See for example @damianavila `"ZenMode"
+plugin <https://github.com/ipython-contrib/IPython-notebook-extensions/blob/master/custom.example.js#L34>`__
+:
+
+.. code:: javascript
+
+
+    // read that as
+    // import custom.zenmode.main as zenmode
+    require(['custom/zenmode/main'],function(zenmode){
+        zenmode.background('images/back12.jpg');
+    })
+
+For the quickest
+^^^^^^^^^^^^^^^^
+
+Try to use `the
+following <https://github.com/ipython/ipython/blob/1.x/IPython/html/static/notebook/js/celltoolbar.js#L367>`__
+to bind a dropdown list to ``cell.metadata.difficulty.select``.
+
+It should be able to take the 4 following values :
+
+-  ``<None>``
+-  ``Easy``
+-  ``Medium``
+-  ``Hard``
+
+We will use it to customiZe the output of the converted notebook
+depending on the tag on each cell
+
+.. code:: python
+
+    %load soln/celldiff.js

+Notebook Basics
+===============
+
+The Notebook dashboard
+----------------------
+
+When you first start the notebook server, your browser will open to the
+notebook dashboard. The dashboard serves as a home page for the
+notebook. Its main purpose is to display the notebooks and files in the
+current directory. For example, here is a screenshot of the dashboard
+page for the ``examples`` directory in the Jupyter repository:
+
+The top of the notebook list displays clickable breadcrumbs of the
+current directory. By clicking on these breadcrumbs or on
+sub-directories in the notebook list, you can navigate your file system.
+
+To create a new notebook, click on the "New" button at the top of the
+list and select a kernel from the dropdown (as seen below). Which
+kernels are listed depend on what's installed on the server. Some of the
+kernels in the screenshot below may not exist as an option to you.
+
+Notebooks and files can be uploaded to the current directory by dragging
+a notebook file onto the notebook list or by the "click here" text above
+the list.
+
+The notebook list shows green "Running" text and a green notebook icon
+next to running notebooks (as seen below). Notebooks remain running
+until you explicitly shut them down; closing the notebook's page is not
+sufficient.
+
+To shutdown, delete, duplicate, or rename a notebook check the checkbox
+next to it and an array of controls will appear at the top of the
+notebook list (as seen below). You can also use the same operations on
+directories and files when applicable.
+
+To see all of your running notebooks along with their directories, click
+on the "Running" tab:
+
+This view provides a convenient way to track notebooks that you start as
+you navigate the file system in a long running notebook server.
+
+Overview of the Notebook UI
+---------------------------
+
+If you create a new notebook or open an existing one, you will be taken
+to the notebook user interface (UI). This UI allows you to run code and
+author notebook documents interactively. The notebook UI has the
+following main areas:
+
+-  Menu
+-  Toolbar
+-  Notebook area and cells
+
+The notebook has an interactive tour of these elements that can be
+started in the "Help:User Interface Tour" menu item.
+
+Modal editor
+------------
+
+Starting with IPython 2.0, the Jupyter Notebook has a modal user
+interface. This means that the keyboard does different things depending
+on which mode the Notebook is in. There are two modes: edit mode and
+command mode.
+
+Edit mode
+~~~~~~~~~
+
+Edit mode is indicated by a green cell border and a prompt showing in
+the editor area:
+
+When a cell is in edit mode, you can type into the cell, like a normal
+text editor.
+
+.. raw:: html
+
+   <div class="alert alert-success">
+
+Enter edit mode by pressing ``Enter`` or using the mouse to click on a
+cell's editor area.
+
+.. raw:: html
+
+   </div>
+
+Command mode
+~~~~~~~~~~~~
+
+Command mode is indicated by a grey cell border with a blue left margin:
+
+When you are in command mode, you are able to edit the notebook as a
+whole, but not type into individual cells. Most importantly, in command
+mode, the keyboard is mapped to a set of shortcuts that let you perform
+notebook and cell actions efficiently. For example, if you are in
+command mode and you press ``c``, you will copy the current cell - no
+modifier is needed.
+
+.. raw:: html
+
+   <div class="alert alert-error">
+
+Don't try to type into a cell in command mode; unexpected things will
+happen!
+
+.. raw:: html
+
+   </div>
+
+.. raw:: html
+
+   <div class="alert alert-success">
+
+Enter command mode by pressing ``Esc`` or using the mouse to click
+*outside* a cell's editor area.
+
+.. raw:: html
+
+   </div>
+
+Mouse navigation
+----------------
+
+All navigation and actions in the Notebook are available using the mouse
+through the menubar and toolbar, which are both above the main Notebook
+area:
+
+The first idea of mouse based navigation is that **cells can be selected
+by clicking on them.** The currently selected cell gets a grey or green
+border depending on whether the notebook is in edit or command mode. If
+you click inside a cell's editor area, you will enter edit mode. If you
+click on the prompt or output area of a cell you will enter command
+mode.
+
+If you are running this notebook in a live session (not on
+http://nbviewer.jupyter.org) try selecting different cells and going
+between edit and command mode. Try typing into a cell.
+
+The second idea of mouse based navigation is that **cell actions usually
+apply to the currently selected cell**. Thus if you want to run the code
+in a cell, you would select it and click the
+
+.. raw:: html
+
+   <button class="btn btn-default btn-xs">
+
+.. raw:: html
+
+   </button>
+
+button in the toolbar or the "Cell:Run" menu item. Similarly, to copy a
+cell you would select it and click the
+
+.. raw:: html
+
+   <button class="btn btn-default btn-xs">
+
+.. raw:: html
+
+   </button>
+
+button in the toolbar or the "Edit:Copy" menu item. With this simple
+pattern, you should be able to do most everything you need with the
+mouse.
+
+Markdown and heading cells have one other state that can be modified
+with the mouse. These cells can either be rendered or unrendered. When
+they are rendered, you will see a nice formatted representation of the
+cell's contents. When they are unrendered, you will see the raw text
+source of the cell. To render the selected cell with the mouse, click
+the
+
+.. raw:: html
+
+   <button class="btn btn-default btn-xs">
+
+.. raw:: html
+
+   </button>
+
+button in the toolbar or the "Cell:Run" menu item. To unrender the
+selected cell, double click on the cell.
+
+Keyboard Navigation
+-------------------
+
+The modal user interface of the Jupyter Notebook has been optimized for
+efficient keyboard usage. This is made possible by having two different
+sets of keyboard shortcuts: one set that is active in edit mode and
+another in command mode.
+
+The most important keyboard shortcuts are ``Enter``, which enters edit
+mode, and ``Esc``, which enters command mode.
+
+In edit mode, most of the keyboard is dedicated to typing into the
+cell's editor. Thus, in edit mode there are relatively few shortcuts. In
+command mode, the entire keyboard is available for shortcuts, so there
+are many more. The ``Help``->``Keyboard Shortcuts`` dialog lists the
+available shortcuts.
+
+We recommend learning the command mode shortcuts in the following rough
+order:
+
+1. Basic navigation: ``enter``, ``shift-enter``, ``up/k``, ``down/j``
+2. Saving the notebook: ``s``
+3. Change Cell types: ``y``, ``m``, ``1-6``, ``t``
+4. Cell creation: ``a``, ``b``
+5. Cell editing: ``x``, ``c``, ``v``, ``d``, ``z``
+6. Kernel operations: ``i``, ``0`` (press twice)

+
+Running Code
+============
+
+First and foremost, the Jupyter Notebook is an interactive environment
+for writing and running code. The notebook is capable of running code in
+a wide range of languages. However, each notebook is associated with a
+single kernel. This notebook is associated with the IPython kernel,
+therefor runs Python code.
+
+Code cells allow you to enter and run code
+------------------------------------------
+
+Run a code cell using ``Shift-Enter`` or pressing the
+
+.. raw:: html
+
+   <button class="btn btn-default btn-xs">
+
+.. raw:: html
+
+   </button>
+
+button in the toolbar above:
+
+.. code:: python
+
+    a = 10
+
+.. code:: python
+
+    print(a)
+
+There are two other keyboard shortcuts for running code:
+
+-  ``Alt-Enter`` runs the current cell and inserts a new one below.
+-  ``Ctrl-Enter`` run the current cell and enters command mode.
+
+Managing the Kernel
+-------------------
+
+Code is run in a separate process called the Kernel. The Kernel can be
+interrupted or restarted. Try running the following cell and then hit
+the
+
+.. raw:: html
+
+   <button class="btn btn-default btn-xs">
+
+.. raw:: html
+
+   </button>
+
+button in the toolbar above.
+
+.. code:: python
+
+    import time
+    time.sleep(10)
+
+If the Kernel dies you will be prompted to restart it. Here we call the
+low-level system libc.time routine with the wrong argument via ctypes to
+segfault the Python interpreter:
+
+.. code:: python
+
+    import sys
+    from ctypes import CDLL
+    # This will crash a Linux or Mac system
+    # equivalent calls can be made on Windows
+    dll = 'dylib' if sys.platform == 'darwin' else 'so.6'
+    libc = CDLL("libc.%s" % dll) 
+    libc.time(-1)  # BOOM!!
+
+Cell menu
+---------
+
+The "Cell" menu has a number of menu items for running code in different
+ways. These includes:
+
+-  Run and Select Below
+-  Run and Insert Below
+-  Run All
+-  Run All Above
+-  Run All Below
+
+Restarting the kernels
+----------------------
+
+The kernel maintains the state of a notebook's computations. You can
+reset this state by restarting the kernel. This is done by clicking on
+the
+
+.. raw:: html
+
+   <button class="btn btn-default btn-xs">
+
+.. raw:: html
+
+   </button>
+
+in the toolbar above.
+
+sys.stdout and sys.stderr
+-------------------------
+
+The stdout and stderr streams are displayed as text in the output area.
+
+.. code:: python
+
+    print("hi, stdout")
+
+.. code:: python
+
+    from __future__ import print_function
+    print('hi, stderr', file=sys.stderr)
+
+Output is asynchronous
+----------------------
+
+All output is displayed asynchronously as it is generated in the Kernel.
+If you execute the next cell, you will see the output one piece at a
+time, not all at the end.
+
+.. code:: python
+
+    import time, sys
+    for i in range(8):
+        print(i)
+        time.sleep(0.5)
+
+Large outputs
+-------------
+
+To better handle large outputs, the output area can be collapsed. Run
+the following cell and then single- or double- click on the active area
+to the left of the output:
+
+.. code:: python
+
+    for i in range(50):
+        print(i)
+
+Beyond a certain point, output will scroll automatically:
+
+.. code:: python
+
+    for i in range(500):
+        print(2**i - 1)

+
+What is the Jupyter Notebook?
+=============================
+
+Introduction
+------------
+
+The Jupyter Notebook is an **interactive computing environment** that
+enables users to author notebook documents that include: - Live code -
+Interactive widgets - Plots - Narrative text - Equations - Images -
+Video
+
+These documents provide a **complete and self-contained record of a
+computation** that can be converted to various formats and shared with
+others using email, `Dropbox <http://dropbox.com>`__, version control
+systems (like git/\ `GitHub <http://github.com>`__) or
+`nbviewer.jupyter.org <http://nbviewer.jupyter.org>`__.
+
+Components
+~~~~~~~~~~
+
+The Jupyter Notebook combines three components:
+
+-  **The notebook web application**: An interactive web application for
+   writing and running code interactively and authoring notebook
+   documents.
+-  **Kernels**: Separate processes started by the notebook web
+   application that runs users' code in a given language and returns
+   output back to the notebook web application. The kernel also handles
+   things like computations for interactive widgets, tab completion and
+   introspection.
+-  **Notebook documents**: Self-contained documents that contain a
+   representation of all content visible in the notebook web
+   application, including inputs and outputs of the computations,
+   narrative text, equations, images, and rich media representations of
+   objects. Each notebook document has its own kernel.
+
+Notebook web application
+------------------------
+
+The notebook web application enables users to:
+
+-  **Edit code in the browser**, with automatic syntax highlighting,
+   indentation, and tab completion/introspection.
+-  **Run code from the browser**, with the results of computations
+   attached to the code which generated them.
+-  See the results of computations with **rich media representations**,
+   such as HTML, LaTeX, PNG, SVG, PDF, etc.
+-  Create and use **interactive JavaScript widgets**, which bind
+   interactive user interface controls and visualizations to reactive
+   kernel side computations.
+-  Author **narrative text** using the
+   `Markdown <https://daringfireball.net/projects/markdown/>`__ markup
+   language.
+-  Build **hierarchical documents** that are organized into sections
+   with different levels of headings.
+-  Include mathematical equations using **LaTeX syntax in Markdown**,
+   which are rendered in-browser by
+   `MathJax <http://www.mathjax.org/>`__.
+
+Kernels
+-------
+
+Through Jupyter's kernel and messaging architecture, the Notebook allows
+code to be run in a range of different programming languages. For each
+notebook document that a user opens, the web application starts a kernel
+that runs the code for that notebook. Each kernel is capable of running
+code in a single programming language and there are kernels available in
+the following languages:
+
+-  Python(https://github.com/ipython/ipython)
+-  Julia (https://github.com/JuliaLang/IJulia.jl)
+-  R (https://github.com/takluyver/IRkernel)
+-  Ruby (https://github.com/minrk/iruby)
+-  Haskell (https://github.com/gibiansky/IHaskell)
+-  Scala (https://github.com/Bridgewater/scala-notebook)
+-  node.js (https://gist.github.com/Carreau/4279371)
+-  Go (https://github.com/takluyver/igo)
+
+The default kernel runs Python code. The notebook provides a simple way
+for users to pick which of these kernels is used for a given notebook.
+
+Each of these kernels communicate with the notebook web application and
+web browser using a JSON over ZeroMQ/WebSockets message protocol that is
+described
+`here <http://ipython.org/ipython-doc/dev/development/messaging.html>`__.
+Most users don't need to know about these details, but it helps to
+understand that "kernels run code."
+
+Notebook documents
+------------------
+
+Notebook documents contain the **inputs and outputs** of an interactive
+session as well as **narrative text** that accompanies the code but is
+not meant for execution. **Rich output** generated by running code,
+including HTML, images, video, and plots, is embeddeed in the notebook,
+which makes it a complete and self-contained record of a computation.
+
+When you run the notebook web application on your computer, notebook
+documents are just **files on your local filesystem with a ``.ipynb``
+extension**. This allows you to use familiar workflows for organizing
+your notebooks into folders and sharing them with others.
+
+Notebooks consist of a **linear sequence of cells**. There are four
+basic cell types:
+
+-  **Code cells:** Input and output of live code that is run in the
+   kernel
+-  **Markdown cells:** Narrative text with embedded LaTeX equations
+-  **Heading cells:** 6 levels of hierarchical organization and
+   formatting
+-  **Raw cells:** Unformatted text that is included, without
+   modification, when notebooks are converted to different formats using
+   nbconvert
+
+Internally, notebook documents are
+**`JSON <http://en.wikipedia.org/wiki/JSON>`__ data** with **binary
+values `base64 <http://en.wikipedia.org/wiki/Base64>`__** encoded. This
+allows them to be **read and manipulated programmatically** by any
+programming language. Because JSON is a text format, notebook documents
+are version control friendly.
+
+**Notebooks can be exported** to different static formats including
+HTML, reStructeredText, LaTeX, PDF, and slide shows
+(`reveal.js <http://lab.hakim.se/reveal-js/#/>`__) using Jupyter's
+``nbconvert`` utility.
+
+Furthermore, any notebook document available from a **public URL on or
+GitHub can be shared** via `nbviewer <http://nbviewer.ipython.org>`__.
+This service loads the notebook document from the URL and renders it as
+a static web page. The resulting web page may thus be shared with others
+**without their needing to install the Jupyter Notebook**.

+
+Markdown Cells
+==============
+
+Text can be added to Jupyter Notebooks using Markdown cells. Markdown is
+a popular markup language that is a superset of HTML. Its specification
+can be found here:
+
+http://daringfireball.net/projects/markdown/
+
+Markdown basics
+---------------
+
+You can make text *italic* or **bold**.
+
+You can build nested itemized or enumerated lists:
+
+-  One
+
+   -  Sublist
+
+      -  This
+
+-  Sublist - That - The other thing
+-  Two
+-  Sublist
+-  Three
+-  Sublist
+
+Now another list:
+
+1. Here we go
+
+   1. Sublist
+   2. Sublist
+
+2. There we go
+3. Now this
+
+You can add horizontal rules:
+
+--------------
+
+Here is a blockquote:
+
+    Beautiful is better than ugly. Explicit is better than implicit.
+    Simple is better than complex. Complex is better than complicated.
+    Flat is better than nested. Sparse is better than dense. Readability
+    counts. Special cases aren't special enough to break the rules.
+    Although practicality beats purity. Errors should never pass
+    silently. Unless explicitly silenced. In the face of ambiguity,
+    refuse the temptation to guess. There should be one-- and preferably
+    only one --obvious way to do it. Although that way may not be
+    obvious at first unless you're Dutch. Now is better than never.
+    Although never is often better than *right* now. If the
+    implementation is hard to explain, it's a bad idea. If the
+    implementation is easy to explain, it may be a good idea. Namespaces
+    are one honking great idea -- let's do more of those!
+
+And shorthand for links:
+
+`Jupyter's website <http://jupyter.org>`__
+
+Headings
+--------
+
+You can add headings by starting a line with one (or multiple) ``#``
+followed by a space, as in the following example:
+
+Heading 1
+=========
+
+Heading 2
+=========
+
+Heading 2.1
+-----------
+
+Heading 2.2
+-----------
+
+Embedded code
+-------------
+
+You can embed code meant for illustration instead of execution in
+Python:
+
+::
+
+    def f(x):
+        """a docstring"""
+        return x**2
+
+or other languages:
+
+::
+
+    if (i=0; i<n; i++) {
+      printf("hello %d\n", i);
+      x += 4;
+    }
+
+LaTeX equations
+---------------
+
+Courtesy of MathJax, you can include mathematical expressions both
+inline: :math:`e^{i\pi} + 1 = 0` and displayed:
+
+.. math:: e^x=\sum_{i=0}^\infty \frac{1}{i!}x^i
+
+Inline expressions can be added by surrounding the latex code with
+``$``:
+
+::
+
+    $e^{i\pi} + 1 = 0$
+
+Expressions on their own line are surrounded by ``$$``:
+
+.. code:: latex
+
+    $$e^x=\sum_{i=0}^\infty \frac{1}{i!}x^i$$
+
+Github flavored markdown (GFM)
+------------------------------
+
+The Notebook webapp support Github flavored markdown meaning that you
+can use triple backticks for code blocks
+
+.. raw:: html
+
+   <pre>
+   ```python
+   print "Hello World"
+   ```
+
+   ```javascript
+   console.log("Hello World")
+   ```
+   </pre>
+
+Gives
+
+.. code:: python
+
+    print "Hello World"
+
+.. code:: javascript
+
+    console.log("Hello World")
+
+And a table like this :
+
+.. raw:: html
+
+   <pre>
+   | This | is   |
+   |------|------|
+   |   a  | table| 
+   </pre>
+
+A nice Html Table
+
++--------+---------+
+| This   | is      |
++========+=========+
+| a      | table   |
++--------+---------+
+
+General HTML
+------------
+
+Because Markdown is a superset of HTML you can even add things like HTML
+tables:
+
+.. raw:: html
+
+   <table>
+
+.. raw:: html
+
+   <tr>
+
+.. raw:: html
+
+   <th>
+
+Header 1
+
+.. raw:: html
+
+   </th>
+
+.. raw:: html
+
+   <th>
+
+Header 2
+
+.. raw:: html
+
+   </th>
+
+.. raw:: html
+
+   </tr>
+
+.. raw:: html
+
+   <tr>
+
+.. raw:: html
+
+   <td>
+
+row 1, cell 1
+
+.. raw:: html
+
+   </td>
+
+.. raw:: html
+
+   <td>
+
+row 1, cell 2
+
+.. raw:: html
+
+   </td>
+
+.. raw:: html
+
+   </tr>
+
+.. raw:: html
+
+   <tr>
+
+.. raw:: html
+
+   <td>
+
+row 2, cell 1
+
+.. raw:: html
+
+   </td>
+
+.. raw:: html
+
+   <td>
+
+row 2, cell 2
+
+.. raw:: html
+
+   </td>
+
+.. raw:: html
+
+   </tr>
+
+.. raw:: html
+
+   </table>
+
+Local files
+-----------
+
+If you have local files in your Notebook directory, you can refer to
+these files in Markdown cells directly:
+
+::
+
+    [subdirectory/]<filename>
+
+For example, in the images folder, we have the Python logo:
+
+::
+
+    <img src="../images/python_logo.svg" />
+
+and a video with the HTML5 video tag:
+
+::
+
+    <video controls src="images/animation.m4v" />
+
+.. raw:: html
+
+   <video controls src="images/animation.m4v" />
+
+These do not embed the data into the notebook file, and require that the
+files exist when you are viewing the notebook.
+
+Security of local files
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Note that this means that the Jupyter notebook server also acts as a
+generic file server for files inside the same tree as your notebooks.
+Access is not granted outside the notebook folder so you have strict
+control over what files are visible, but for this reason it is highly
+recommended that you do not run the notebook server with a notebook
+directory at a high level in your filesystem (e.g. your home directory).
+
+When you run the notebook in a password-protected manner, local file
+access is restricted to authenticated users unless read-only views are
+active.

+Contents API
+============
+
+.. currentmodule:: notebook.services.contents
+
+The Jupyter Notebook web application provides a graphical interface for
+creating, opening, renaming, and deleting files in a virtual filesystem.
+
+The :class:`~manager.ContentsManager` class defines an abstract
+API for translating these interactions into operations on a particular storage
+medium. The default implementation,
+:class:`~filemanager.FileContentsManager`, uses the local
+filesystem of the server for storage and straightforwardly serializes notebooks
+into JSON.  Users can override these behaviors by supplying custom subclasses
+of ContentsManager.
+
+This section describes the interface implemented by ContentsManager subclasses.
+We refer to this interface as the **Contents API**.
+
+Data Model

+
+.. currentmodule:: notebook.services.contents.manager
+
+Filesystem Entities
+~~~~~~~~~~~~~~~~~~~
+.. _notebook models:
+
+ContentsManager methods represent virtual filesystem entities as dictionaries,
+which we refer to as **models**.
+
+Models may contain the following entries:
+
++--------------------+-----------+------------------------------+
+| Key                | Type      |Info                          |
++====================+===========+==============================+
+|**name**            |unicode    |Basename of the entity.       |
++--------------------+-----------+------------------------------+
+|**path**            |unicode    |Full                          |

+|                    |           |path to the entity.           |
++--------------------+-----------+------------------------------+
+|**type**            |unicode    |The entity type. One of       |
+|                    |           |``"notebook"``, ``"file"`` or |
+|                    |           |``"directory"``.              |
++--------------------+-----------+------------------------------+
+|**created**         |datetime   |Creation date of the entity.  |
++--------------------+-----------+------------------------------+
+|**last_modified**   |datetime   |Last modified date of the     |
+|                    |           |entity.                       |
++--------------------+-----------+------------------------------+
+|**content**         |variable   |The "content" of the entity.  |
+|                    |           |(:ref:`See                    |
+|                    |           |Below<modelcontent>`)         |
++--------------------+-----------+------------------------------+
+|**mimetype**        |unicode or |The mimetype of ``content``,  |
+|                    |``None``   |if any.  (:ref:`See           |
+|                    |           |Below<modelcontent>`)         |
++--------------------+-----------+------------------------------+
+|**format**          |unicode or |The format of ``content``,    |
+|                    |``None``   |if any. (:ref:`See            |
+|                    |           |Below<modelcontent>`)         |
++--------------------+-----------+------------------------------+
+
+.. _modelcontent:
+
+Certain model fields vary in structure depending on the ``type`` field of the
+model.  There are three model types: **notebook**, **file**, and **directory** .
+
+- ``notebook`` models
+    - The ``format`` field is always ``"json"``.
+    - The ``mimetype`` field is always ``None``.
+    - The ``content`` field contains a
+      :class:`nbformat.notebooknode.NotebookNode` representing the .ipynb file
+      represented by the model.  See the `NBFormat`_ documentation for a full
+      description.
+
+- ``file`` models
+    - The ``format`` field is either ``"text"`` or ``"base64"``.
+    - The ``mimetype`` field is ``text/plain`` for text-format models and
+      ``application/octet-stream`` for base64-format models.
+    - The ``content`` field is always of type ``unicode``.  For text-format
+      file models, ``content`` simply contains the file's bytes after decoding
+      as UTF-8.  Non-text (``base64``) files are read as bytes, base64 encoded,
+      and then decoded as UTF-8.
+
+- ``directory`` models
+    - The ``format`` field is always ``"json"``.
+    - The ``mimetype`` field is always ``None``.
+    - The ``content`` field contains a list of :ref:`content-free<contentfree>`
+      models representing the entities in the directory.
+
+.. note::
+
+   .. _contentfree:
+
+   In certain circumstances, we don't need the full content of an entity to
+   complete a Contents API request.  In such cases, we omit the ``mimetype``,
+   ``content``, and ``format`` keys from the model. This most commonly occurs
+   when listing a directory, in which circumstance we represent files within
+   the directory as content-less models to avoid having to recursively traverse
+   and serialize the entire filesystem.
+
+**Sample Models**

+        'created': datetime.datetime(2015, 7, 25, 20, 17, 33, 271931),
+        'format': None,
+        'last_modified': datetime.datetime(2015, 7, 25, 20, 17, 33, 271931),

+        'name': 'a.ipynb',
+        'path': 'foo/a.ipynb',
+        'type': 'notebook',
+        'writable': True
+    }
+
+
+API Paths
+~~~~~~~~~
+.. _apipaths:
+
+ContentsManager methods represent the locations of filesystem resources as
+**API-style paths**.  Such paths are interpreted as relative to the root
+directory of the notebook server.  For compatibility across systems, the
+following guarantees are made:
+
+* Paths are always ``unicode``, not ``bytes``.
+* Paths are not URL-escaped.
+* Paths are always forward-slash (/) delimited, even on Windows.
+* Leading and trailing slashes are stripped.  For example, ``/foo/bar/buzz/``
+  becomes ``foo/bar/buzz``.
+* The empty string (``""``) represents the root directory.
+
+
+Writing a Custom ContentsManager
+--------------------------------
+
+The default ContentsManager is designed for users running the notebook as an
+application on a personal computer.  It stores notebooks as .ipynb files on the
+local filesystem, and it maps files and directories in the Notebook UI to files
+and directories on disk.  It is possible to override how notebooks are stored
+by implementing your own custom subclass of ``ContentsManager``. For example,
+if you deploy the notebook in a context where you don't trust or don't have
+access to the filesystem of the notebook server, it's possible to write your
+own ContentsManager that stores notebooks and files in a database.
+
+
+Required Methods
+~~~~~~~~~~~~~~~~
+
+A minimal complete implementation of a custom
+:class:`~manager.ContentsManager` must implement the following
+methods:
+
+.. autosummary::
+   ContentsManager.get
+   ContentsManager.save
+   ContentsManager.delete_file
+   ContentsManager.rename_file
+   ContentsManager.file_exists
+   ContentsManager.dir_exists
+   ContentsManager.is_hidden
+
+
+Customizing Checkpoints
+-----------------------
+
+TODO:
+
+
+Testing
+-------
+.. currentmodule:: notebook.services.contents.tests
+
+:mod:`notebook.services.contents.tests` includes several test suites written
+against the abstract Contents API.  This means that an excellent way to test a
+new ContentsManager subclass is to subclass our tests to make them use your
+ContentsManager.
+
+.. note::
+
+   PGContents_ is an example of a complete implementation of a custom
+   ``ContentsManager``.  It stores notebooks and files in PostgreSQL_ and encodes
+   directories as SQL relations.  PGContents also provides an example of how to
+   re-use the notebook's tests.

+Custom front-end extensions
+===========================
+
+This describes the basic steps to write a JavaScript extension for the Jupyter
+notebook front-end. This allows you to customize the behaviour of the various
+pages like the dashboard, the notebook, or the text editor.
+
+The structure of a front-end extension
+--------------------------------------
+
+.. note::
+
+    The notebook front-end and Javascript API are not stable, and are subject
+    to a lot of changes. Any extension written for the current notebook is
+    almost guaranteed to break in the next release.
+
+.. _AMD module: https://en.wikipedia.org/wiki/Asynchronous_module_definition
+
+A front-end extension is a JavaScript file that defines an `AMD module`_
+which exposes at least a function called ``load_ipython_extension``, which
+takes no arguments. We will not get into the details of what each of these
+terms consists of yet, but here is the minimal code needed for a working
+extension:
+
+.. code:: javascript
+
+    // file my_extension/main.js
+
+    define(function(){
+
+        function load_ipython_extension(){
+            console.info('this is my first extension');
+        }
+
+        return {
+            load_ipython_extension: load_ipython_extension
+        };
+    });
+
+.. note::
+
+    Although for historical reasons the function is called
+    ``load_ipython_extension``, it does apply to the Jupyter notebook in
+    general, and will work regardless of the kernel in use.
+
+If you are familiar with JavaScript, you can use this template to require any
+Jupyter module and modify its configuration, or do anything else in client-side
+Javascript. Your extension will be loaded at the right time during the notebook
+page initialisation for you to set up a listener for the various events that
+the page can trigger.
+
+You might want access to the current instances of the various Jupyter notebook
+components on the page, as opposed to the classes defined in the modules. The
+current instances are exposed by a module named ``base/js/namespace``. If you
+plan on accessing instances on the page, you should ``require`` this module
+rather than accessing the global variable ``Jupyter``, which will be removed in
+future. The following example demonstrates how to access the current notebook
+instance:
+
+.. code:: javascript
+
+    // file my_extension/main.js
+
+    define([
+        'base/js/namespace'
+    ], function(
+        Jupyter
+    ) {
+        function load_ipython_extension() {
+            console.log(
+                'This is the current notebook application instance:',
+                Jupyter.notebook
+            );
+        }
+
+        return {
+            load_ipython_extension: load_ipython_extension
+        };
+    });
+
+
+Modifying key bindings
+----------------------
+
+One of the abilities of extensions is to modify key bindings, although once
+again this is an API which is not guaranteed to be stable. However, custom key
+bindings are frequently requested, and are helpful to increase accessibility,
+so in the following we show how to access them.
+
+Here is an example of an extension that will unbind the shortcut ``0,0`` in
+command mode, which normally restarts the kernel, and bind ``0,0,0`` in its
+place:
+
+.. code:: javascript
+
+    // file my_extension/main.js
+
+    define([
+        'base/js/namespace'
+    ], function(
+        Jupyter
+    ) {
+
+        function load_ipython_extension() {
+            Jupyter.keyboard_manager.command_shortcuts.remove_shortcut('0,0');
+            Jupyter.keyboard_manager.command_shortcuts.add_shortcut('0,0,0', 'jupyter-notebook:restart-kernel');
+        }
+
+        return {
+            load_ipython_extension: load_ipython_extension
+        };
+    });
+
+.. note::
+
+    The standard keybindings might not work correctly on non-US keyboards.
+    Unfortunately, this is a limitation of browser implementations and the
+    status of keyboard event handling on the web in general. We appreciate your
+    feedback if you have issues binding keys, or have any ideas to help improve
+    the situation.
+
+You can see that I have used the **action name**
+``jupyter-notebook:restart-kernel`` to bind the new shortcut. There is no API
+yet to access the list of all available *actions*, though the following in the
+JavaScript console of your browser on a notebook page should give you an idea
+of what is available:
+
+.. code:: javascript
+
+    Object.keys(require('base/js/namespace').actions._actions);
+
+In this example, we changed a keyboard shortcut in **command mode**; you
+can also customize keyboard shortcuts in **edit mode**.
+However, most of the keyboard shortcuts in edit mode are handled by CodeMirror,
+which supports custom key bindings via a completely different API.
+
+
+Defining and registering your own actions
+-----------------------------------------
+
+As part of your front-end extension, you may wish to define actions, which can
+be attached to toolbar buttons, or called from the command palette. Here is an
+example of an extension that defines a (not very useful!) action to show an
+alert, and adds a toolabr button using the full action name:
+
+.. code:: javascript
+
+    // file my_extension/main.js
+
+    define([
+        'base/js/namespace'
+    ], function(
+        Jupyter
+    ) {
+        function load_ipython_extension() {
+
+            var handler = function () {
+                alert('this is an alert from my_extension!');
+            };
+
+            var action = {
+                icon: 'fa-comment-o', // a font-awesome class used on buttons, etc
+                help    : 'Show an alert',
+                help_index : 'zz',
+                handler : handler
+            };
+            var prefix = 'my_extension';
+            var action_name = 'show-alert';
+
+            var full_action_name = Jupyter.actions.register(action, name, prefix); // returns 'my_extension:show-alert'
+            Jupyter.toolbar.add_buttons_group([full_action_name]);
+        }
+
+        return {
+            load_ipython_extension: load_ipython_extension
+        };
+    });
+
+Every action needs a name, which, when joined with its prefix to make the full
+action name, should be unique. Built-in actions, like the
+``jupyter-notebook:restart-kernel`` we bound in the earlier
+`Modifying key bindings`_ example, use the prefix ``jupyter-notebook``. For
+actions defined in an extension, it makes sense to use the extension name as
+the prefix. For the action name, the following guidelines should be considered:
+
+.. adapted from notebook/static/notebook/js/actions.js
+
+* First pick a noun and a verb for the action. For example, if the action is
+  "restart kernel," the verb is "restart" and the noun is "kernel".
+* Omit terms like "selected" and "active" by default, so "delete-cell", rather
+  than "delete-selected-cell". Only provide a scope like "-all-" if it is other
+  than the default "selected" or "active" scope.
+* If an action has a secondary action, separate the secondary action with
+  "-and-", so "restart-kernel-and-clear-output".
+* Use above/below or previous/next to indicate spatial and sequential
+  relationships.
+* Don't ever use before/after as they have a temporal connotation that is
+  confusing when used in a spatial context.
+* For dialogs, use a verb that indicates what the dialog will accomplish, such
+  as "confirm-restart-kernel".
+
+
+Installing and enabling extensions
+----------------------------------
+
+You can install your nbextension with the command::
+
+    jupyter nbextension install path/to/my_extension/ [--user|--sys-prefix]
+
+The default installation is system-wide. You can use ``--user`` to do a per-user installation,
+or ``--sys-prefix`` to install to Python's prefix (e.g. in a virtual or conda environment).
+Where my_extension is the directory containing the Javascript files.
+This will copy it to a Jupyter data directory (the exact location is platform
+dependent - see :ref:`jupyter_path`).
+
+For development, you can use the ``--symlink`` flag to symlink your extension
+rather than copying it, so there's no need to reinstall after changes.
+
+To use your extension, you'll also need to **enable** it, which tells the
+notebook interface to load it. You can do that with another command::
+
+    jupyter nbextension enable my_extension/main [--sys-prefix]
+
+The argument refers to the Javascript module containing your
+``load_ipython_extension`` function, which is ``my_extension/main.js`` in this
+example. There is a corresponding ``disable`` command to stop using an
+extension without uninstalling it.
+
+.. versionchanged:: 4.2
+
+    Added ``--sys-prefix`` argument

+Custom request handlers
+=======================
+
+The notebook webserver can be interacted with using a well `defined
+RESTful
+API <http://petstore.swagger.io/?url=https://raw.githubusercontent.com/jupyter/jupyter-js-services/master/rest_api.yaml>`__.
+You can define custom RESTful API handlers in addition to the ones
+provided by the notebook. As described below, to define a custom handler
+you need to first write a notebook server extension. Then, in the
+extension, you can register the custom handler.
+
+Writing a notebook server extension
+-----------------------------------
+
+The notebook webserver is written in Python, hence your server extension
+should be written in Python too. Server extensions, like IPython
+extensions, are Python modules that define a specially named load
+function, ``load_jupyter_server_extension``. This function is called
+when the extension is loaded.
+
+.. code:: python
+
+    def load_jupyter_server_extension(nb_server_app):
+        """
+        Called when the extension is loaded.
+        
+        Args:
+            nb_server_app (NotebookWebApplication): handle to the Notebook webserver instance.
+        """
+        pass
+
+To get the notebook server to load your custom extension, you'll need to
+add it to the list of extensions to be loaded. You can do this using the
+config system. ``NotebookApp.server_extensions`` is a config variable
+which is an array of strings, each a Python module to be imported.
+Because this variable is notebook config, you can set it two different
+ways, using config files or via the command line.
+
+For example, to get your extension to load via the command line add a
+double dash before the variable name, and put the Python array in
+double quotes. If your package is "mypackage" and module is
+"mymodule", this would look like
+``jupyter notebook --NotebookApp.server_extensions="['mypackage.mymodule']"``
+.
+Basically the string should be Python importable.
+
+Alternatively, you can have your extension loaded regardless of the
+command line args by setting the variable in the Jupyter config file.
+The default location of the Jupyter config file is
+``~/.jupyter/profile_default/jupyter_notebook_config.py``. Then, inside
+the config file, you can use Python to set the variable. For example,
+the following config does the same as the previous command line example
+[1].
+
+.. code:: python
+
+    c = get_config()
+    c.NotebookApp.server_extensions = [
+        'mypackage.mymodule'
+    ]
+
+Before continuing, it's a good idea to verify that your extension is
+being loaded. Use a print statement to print something unique. Launch
+the notebook server and you should see your statement printed to the
+console.
+
+Registering custom handlers
+---------------------------
+
+Once you've defined a server extension, you can register custom handlers
+because you have a handle to the Notebook server app instance
+(``nb_server_app`` above). However, you first need to define your custom
+handler. To declare a custom handler, inherit from
+``notebook.base.handlers.IPythonHandler``. The example below[1] is a
+Hello World handler:
+
+.. code:: python
+
+    from notebook.base.handlers import IPythonHandler
+
+    class HelloWorldHandler(IPythonHandler):
+        def get(self):
+            self.finish('Hello, world!')
+
+The Jupyter Notebook server use
+`Tornado <http://www.tornadoweb.org/en/stable/>`__ as its web framework.
+For more information on how to implement request handlers, refer to the
+`Tornado documentation on the
+matter <http://www.tornadoweb.org/en/stable/web.html#request-handlers>`__.
+
+After defining the handler, you need to register the handler with the
+Notebook server. See the following example:
+
+.. code:: python
+
+    web_app = nb_server_app.web_app
+    host_pattern = '.*$'
+    route_pattern = url_path_join(web_app.settings['base_url'], '/hello')
+    web_app.add_handlers(host_pattern, [(route_pattern, HelloWorldHandler)])
+
+Putting this together with the extension code, the example looks like the 
+following:
+
+.. code:: python
+
+    from notebook.utils import url_path_join
+    from notebook.base.handlers import IPythonHandler
+
+    class HelloWorldHandler(IPythonHandler):
+        def get(self):
+            self.finish('Hello, world!')
+
+    def load_jupyter_server_extension(nb_server_app):
+        """
+        Called when the extension is loaded.
+        
+        Args:
+            nb_server_app (NotebookWebApplication): handle to the Notebook webserver instance.
+        """
+        web_app = nb_server_app.web_app
+        host_pattern = '.*$'
+        route_pattern = url_path_join(web_app.settings['base_url'], '/hello')
+        web_app.add_handlers(host_pattern, [(route_pattern, HelloWorldHandler)])

+File save hooks
+===============
+
+You can configure functions that are run whenever a file is saved. There are
+two hooks available:
+
+* ``ContentsManager.pre_save_hook`` runs on the API path and model with content.
+  This can be used for things like stripping output that people don't like
+  adding to VCS noise.
+* ``FileContentsManager.post_save_hook`` runs on the filesystem path and model
+  without content. This could be used to commit changes after every save, for
+  instance.
+
+They are both called with keyword arguments::
+
+    pre_save_hook(model=model, path=path, contents_manager=cm)
+    post_save_hook(model=model, os_path=os_path, contents_manager=cm)
+
+Examples
+--------
+
+These can both be added to :file:`jupyter_notebook_config.py`.
+
+A pre-save hook for stripping output::

+            f.write(script)
+    c.FileContentsManager.post_save_hook = script_post_save
+
+This could be a simple call to ``jupyter nbconvert --to script``, but spawning

+
+Configuring the notebook frontend
+=================================
+
+.. note::
+
+    The ability to configure the notebook frontend UI and preferences is
+    still a work in progress.
+
+This document is a rough explanation on how you can persist some configuration
+options for the notebook JavaScript.
+
+There is no exhaustive list of all the configuration options as most options
+are passed down to other libraries, which means that non valid
+configuration can be ignored without any error messages.
+
+
+How front end configuration works
+---------------------------------
+The frontend configuration system works as follows:
+
+  - get a handle of a configurable JavaScript object.
+  - access its configuration attribute.
+  - update its configuration attribute with a JSON patch.
+
+
+Example - Changing the notebook's default indentation
+-----------------------------------------------------
+This example explains how to change the default setting ``indentUnit``
+for CodeMirror Code Cells::
+
+    var cell = Jupyter.notebook.get_selected_cell();
+    var config = cell.config;
+    var patch = {
+          CodeCell:{
+            cm_config:{indentUnit:2}
+          }
+        }
+    config.update(patch)
+
+You can enter the previous snippet in your browser's JavaScript console once.
+Then reload the notebook page in your browser. Now, the preferred indent unit
+should be equal to two spaces. The custom setting persists and you do not need
+to reissue the patch on new notebooks.
+
+``indentUnit``, used in this example, is one of the many `CodeMirror options
+<https://codemirror.net/doc/manual.html#option_indentUnit>`_ which are available
+for configuration.
+
+
+Example - Restoring the notebook's default indentation
+------------------------------------------------------
+If you want to restore a notebook frontend preference to its default value,
+you will enter a JSON patch with a ``null`` value for the preference setting.
+
+For example, let's restore the indent setting ``indentUnit`` to its default of
+four spaces. Enter the following code snippet in your JavaScript console::
+
+    var cell = Jupyter.notebook.get_selected_cell();
+    var config = cell.config;
+    var patch = {
+          CodeCell:{
+            cm_config:{indentUnit: null} # only change here.
+          }
+        }
+    config.update(patch)
+
+Reload the notebook in your browser and the default indent should again be two
+spaces.
+
+Persisting configuration settings
+---------------------------------
+Under the hood, Jupyter will persist the preferred configuration settings in
+``~/.jupyter/nbconfig/<section>.json``, with ``<section>``
+taking various value depending on the page where the configuration is issued.
+``<section>`` can take various values like ``notebook``, ``tree``, and

+
+The Jupyter Notebook
+====================
+
+Introduction
+------------
+
+The notebook extends the console-based approach to interactive computing in
+a qualitatively new direction, providing a web-based application suitable for
+capturing the whole computation process: developing, documenting, and
+executing code, as well as communicating the results.  The Jupyter notebook
+combines two components:
+
+**A web application**: a browser-based tool for interactive authoring of
+documents which combine explanatory text, mathematics, computations and their
+rich media output.
+
+**Notebook documents**: a representation of all content visible in the web
+application, including inputs and outputs of the computations, explanatory
+text, mathematics, images, and rich media representations of objects.
+
+.. seealso::
+
+    See the :ref:`installation guide <jupyter:install>` on how to install the notebook and its dependencies.
+
+
+Main features of the web application
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* In-browser editing for code, with automatic syntax highlighting,
+  indentation, and tab completion/introspection.
+
+* The ability to execute code from the browser, with the results of
+  computations attached to the code which generated them.
+
+* Displaying the result of computation using rich media representations, such
+  as HTML, LaTeX, PNG, SVG, etc. For example, publication-quality figures
+  rendered by the matplotlib_ library, can be included inline.
+
+* In-browser editing for rich text using the Markdown_ markup language, which
+  can provide commentary for the code, is not limited to plain text.
+
+* The ability to easily include mathematical notation within markdown cells
+  using LaTeX, and rendered natively by MathJax_.
+
+
+
+.. _MathJax: http://www.mathjax.org/
+
+
+Notebook documents
+~~~~~~~~~~~~~~~~~~
+Notebook documents contains the inputs and outputs of a interactive session as
+well as additional text that accompanies the code but is not meant for
+execution.  In this way, notebook files can serve as a complete computational
+record of a session, interleaving executable code with explanatory text,
+mathematics, and rich representations of resulting objects. These documents
+are internally JSON_ files and are saved with the ``.ipynb`` extension. Since
+JSON is a plain text format, they can be version-controlled and shared with
+colleagues.
+
+.. _JSON: http://en.wikipedia.org/wiki/JSON
+
+Notebooks may be exported to a range of static formats, including HTML (for
+example, for blog posts), reStructuredText, LaTeX, PDF, and slide shows, via
+the nbconvert_ command.
+
+Furthermore, any  ``.ipynb`` notebook document available from a public
+URL can be shared via the `Jupyter Notebook Viewer <nbviewer>`_ (nbviewer_).
+This service loads the notebook document from the URL and renders it as a
+static web page.  The results may thus be shared with a colleague, or as a
+public blog post, without other users needing to install the Jupyter notebook 
+themselves.  In effect, nbviewer_ is simply nbconvert_ as
+a web service, so you can do your own static conversions with nbconvert, 
+without relying on nbviewer.
+
+
+
+.. seealso::
+
+    :ref:`Details on the notebook JSON file format <nbformat:notebook_file_format>`
+
+
+Starting the notebook server
+----------------------------
+
+You can start running a notebook server from the command line using the
+following command::
+
+    jupyter notebook
+
+This will print some information about the notebook server in your console,
+and open a web browser to the URL of the web application (by default,
+``http://127.0.0.1:8888``).
+
+The landing page of the Jupyter notebook web application, the **dashboard**,
+shows the notebooks currently available in the notebook directory (by default,
+the directory from which the notebook server was started).
+
+You can create new notebooks from the dashboard with the ``New Notebook``
+button, or open existing ones by clicking on their name.  You can also drag
+and drop ``.ipynb`` notebooks and standard ``.py`` Python source code files
+into the notebook list area.
+
+When starting a notebook server from the command line, you can also open a
+particular notebook directly, bypassing the dashboard, with ``jupyter notebook
+my_notebook.ipynb``. The ``.ipynb`` extension is assumed if no extension is
+given.
+
+When you are inside an open notebook, the `File | Open...` menu option will
+open the dashboard in a new browser tab, to allow you to open another notebook
+from the notebook directory or to create a new notebook.
+
+
+.. note::
+
+   You can start more than one notebook server at the same time, if you want
+   to work on notebooks in different directories.  By default the first
+   notebook server starts on port 8888, and later notebook servers search for
+   ports near that one.  You can also manually specify the port with the
+   ``--port`` option.
+
+Creating a new notebook document
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A new notebook may be created at any time, either from the dashboard, or using
+the `File | New` menu option from within an active notebook. The new notebook
+is created within the same directory and will open in a new browser tab. It
+will also be reflected as a new entry in the notebook list on the dashboard.
+
+
+Opening notebooks
+~~~~~~~~~~~~~~~~~
+An open notebook has **exactly one** interactive session connected to an
+:ref:`IPython kernel <ipythonzmq>`, which will execute code sent by the user
+and communicate back results.  This kernel remains active if the web browser
+window is closed, and reopening the same notebook from the dashboard will
+reconnect the web application to the same kernel. In the dashboard, notebooks
+with an active kernel have a ``Shutdown`` button next to them, whereas
+notebooks without an active kernel have a ``Delete`` button in its place.
+
+Other clients may connect to the same underlying IPython kernel.
+The notebook server always prints to the terminal the full details of
+how to connect to each kernel, with messages such as the following::
+
+    [NotebookApp] Kernel started: 87f7d2c0-13e3-43df-8bb8-1bd37aaf3373
+
+This long string is the kernel's ID which is sufficient for getting the
+information necessary to connect to the kernel.  You can also request this
+connection data by running the ``%connect_info`` :ref:`magic
+<magics_explained>`. This will print the same ID information as well as the
+content of the JSON data structure it contains.
+
+You can then, for example, manually start a Qt console connected to the *same*
+kernel from the command line, by passing a portion of the ID::
+
+    $ ipython qtconsole --existing 87f7d2c0
+
+Without an ID, ``--existing`` will  connect to the most recently
+started kernel. This can also be done by running the ``%qtconsole``
+:ref:`magic <magics_explained>` in the notebook.
+
+.. seealso::
+
+    :ref:`ipythonzmq`
+
+Notebook user interface
+-----------------------
+
+When you create a new notebook document, you will be presented with the
+**notebook name**, a **menu bar**, a **toolbar** and an empty **code
+cell**.
+
+**notebook name**: The name of the notebook document is displayed at the top
+of the page, next to the ``IP[y]: Notebook`` logo. This name reflects the name
+of the ``.ipynb`` notebook document file.  Clicking on the notebook name
+brings up a dialog which allows you to rename it. Thus, renaming a notebook
+from "Untitled0" to "My first notebook" in the browser, renames the
+``Untitled0.ipynb`` file to ``My first notebook.ipynb``.
+
+**menu bar**: The menu bar presents different options that may be used to
+manipulate the way the notebook functions.
+
+**toolbar**: The tool bar gives a quick way of performing the most-used
+operations within the notebook, by clicking on an icon.
+
+**code cell**: the default type of cell, read on for an explanation of cells
+
+.. note:: 
+
+    As of notebook version 4.1, the user interface allows for multiple cells to
+    be selected.  The ``quick celltype selector``, found in the menubar, will
+    display a dash ``-`` when multiple cells are selected to indicate that the
+    type of the cells in the selection might not be unique. The quick selector
+    can still be used to change the type of the selection and will change the
+    type of all the currently selected cells.
+
+
+Structure of a notebook document
+--------------------------------
+
+The notebook consists of a sequence of cells.  A cell is a multi-line
+text input field, and its contents can be executed by using
+:kbd:`Shift-Enter`, or by clicking either the "Play" button the toolbar, or
+`Cell | Run` in the menu bar.  The execution behavior of a cell is determined
+the cell's type.  There are four types of cells: **code cells**, **markdown
+cells**, **raw cells** and **heading cells**.  Every cell starts off
+being a **code cell**, but its type can be changed by using a dropdown on the
+toolbar (which will be "Code", initially), or via :ref:`keyboard shortcuts
+<keyboard-shortcuts>`.
+
+For more information on the different things you can do in a notebook,
+see the `collection of examples
+<http://nbviewer.jupyter.org/github/jupyter/notebook/tree/master/docs/source/examples/Notebook/>`_.
+
+Code cells
+~~~~~~~~~~
+A *code cell* allows you to edit and write new code, with full syntax
+highlighting and tab completion. By default, the language associated to a code
+cell is Python, but other languages, such as ``Julia`` and ``R``, can be
+handled using :ref:`cell magic commands <magics_explained>`.
+
+When a code cell is executed, code that it contains is sent to the kernel
+associated with the notebook.  The results that are returned from this
+computation  are then displayed in the notebook as the cell's *output*. The
+output is not limited to text, with many other possible forms of output are
+also possible, including ``matplotlib`` figures and HTML tables (as used, for
+example, in the ``pandas`` data analysis package). This is known as IPython's
+*rich display* capability.
+
+.. seealso::
+
+   `Rich Output`_  example notebook
+
+Markdown cells
+~~~~~~~~~~~~~~
+You can document the computational process in a literate way, alternating
+descriptive text with code, using *rich text*. In IPython this is accomplished
+by marking up text with the Markdown language. The corresponding cells are
+called *Markdown cells*. The Markdown language provides a simple way to
+perform this text markup, that is, to specify which parts of the text should
+be emphasized (italics), bold, form lists, etc.
+
+
+When a Markdown cell is executed, the Markdown code is converted into
+the corresponding formatted rich text. Markdown allows arbitrary HTML code for
+formatting.
+
+Within Markdown cells, you can also include *mathematics* in a straightforward
+way, using standard LaTeX notation: ``$...$`` for inline mathematics and
+``$$...$$`` for displayed mathematics. When the Markdown cell is executed,
+the LaTeX portions are automatically rendered in the HTML output as equations
+with high quality typography. This is made possible by MathJax_, which
+supports a `large subset <mathjax_tex>`_ of LaTeX functionality
+
+.. _mathjax_tex: http://docs.mathjax.org/en/latest/tex.html
+
+Standard mathematics environments defined by LaTeX and AMS-LaTeX (the
+`amsmath` package) also work, such as
+``\begin{equation}...\end{equation}``, and ``\begin{align}...\end{align}``.
+New LaTeX macros may be defined using standard methods,
+such as ``\newcommand``, by placing them anywhere *between math delimiters* in
+a Markdown cell. These definitions are then available throughout the rest of
+the IPython session.
+
+.. seealso::
+
+    `Markdown Cells`_ example notebook
+
+Raw cells
+~~~~~~~~~
+
+*Raw* cells provide a place in which you can write *output* directly.
+Raw cells are not evaluated by the notebook.
+When passed through nbconvert_, raw cells arrive in the
+destination format unmodified. For example, this allows you to type full LaTeX
+into a raw cell, which will only be rendered by LaTeX after conversion by
+nbconvert.
+
+Heading cells
+~~~~~~~~~~~~~
+
+If you want to provide structure for your document, you can use markdown
+headings. Markdown headings consist of 1 to 6 hash # signs ``#`` followed by a
+space and the title of your section. The markdown heading will be converted
+to a clickable link for a section of the notebook. It is also used as a hint
+when exporting to other document formats, like PDF.
+We recommend using only one markdown header in a cell and limit the cell's
+content to the header text. For flexibility of text format conversion, we
+suggest placing additional text in the next notebook cell.
+
+Basic workflow
+--------------
+
+The normal workflow in a notebook is, then, quite similar to a standard
+IPython session, with the difference that you can edit cells in-place multiple
+times until you obtain the desired results, rather than having to
+rerun separate scripts with the ``%run`` magic command.
+
+
+Typically, you will work on a computational problem in pieces, organizing
+related ideas into cells and moving forward once previous parts work
+correctly. This is much more convenient for interactive exploration than
+breaking up a computation into scripts that must be executed together, as was
+previously necessary, especially if parts of them take a long time to run.
+
+At certain moments, it may be necessary to interrupt a calculation which is
+taking too long to complete. This may be done with the `Kernel | Interrupt`
+menu option, or the :kbd:`Ctrl-m i` keyboard shortcut.
+Similarly, it may be necessary or desirable to restart the whole computational
+process, with the `Kernel | Restart` menu option or :kbd:`Ctrl-m .`
+shortcut.
+
+A notebook may be downloaded in either a ``.ipynb`` or ``.py`` file from the
+menu option `File | Download as`. Choosing the ``.py`` option downloads a
+Python ``.py`` script, in which all rich output has been removed and the
+content of markdown cells have been inserted as comments.
+
+.. seealso::
+
+    `Running Code in the Jupyter Notebook`_ example notebook
+
+    `Notebook Basics`_ example notebook
+
+    :ref:`a warning about doing "roundtrip" conversions <note_about_roundtrip>`.
+
+.. _keyboard-shortcuts:
+
+Keyboard shortcuts
+~~~~~~~~~~~~~~~~~~
+All actions in the notebook can be performed with the mouse, but keyboard
+shortcuts are also available for the most common ones. The essential shortcuts
+to remember are the following:
+
+* :kbd:`Shift-Enter`:  run cell
+    Execute the current cell, show output (if any), and jump to the next cell
+    below. If :kbd:`Shift-Enter` is invoked on the last cell, a new code
+    cell will also be created. Note that in the notebook, typing :kbd:`Enter`
+    on its own *never* forces execution, but rather just inserts a new line in
+    the current cell. :kbd:`Shift-Enter` is equivalent to clicking the
+    ``Cell | Run`` menu item.
+
+* :kbd:`Ctrl-Enter`: run cell in-place
+    Execute the current cell as if it were in "terminal mode", where any
+    output is shown, but the cursor *remains* in the current cell. The cell's
+    entire contents are selected after execution, so you can just start typing
+    and only the new input will be in the cell. This is convenient for doing
+    quick experiments in place, or for querying things like filesystem
+    content, without needing to create additional cells that you may not want
+    to be saved in the notebook.
+
+* :kbd:`Alt-Enter`: run cell, insert below
+    Executes the current cell, shows the output, and inserts a *new*
+    cell between the current cell and the cell below (if one exists). This
+    is thus a shortcut for the sequence :kbd:`Shift-Enter`, :kbd:`Ctrl-m a`.
+    (:kbd:`Ctrl-m a` adds a new cell above the current one.)
+
+* :kbd:`Esc` and :kbd:`Enter`: Command mode and edit mode
+    In command mode, you can easily navigate around the notebook using keyboard
+    shortcuts. In edit mode, you can edit text in cells.
+
+For the full list of available shortcuts, click :guilabel:`Help`,
+:guilabel:`Keyboard Shortcuts` in the notebook menus.
+
+Plotting
+--------
+One major feature of the Jupyter notebook is the ability to display plots that 
+are the output of running code cells. The IPython kernel is designed to work 
+seamlessly with the matplotlib_ plotting library to provide this functionality.  
+Specific plotting library integration is a feature of the kernel.
+
+Installing kernels
+------------------
+
+For information on how to install a Python kernel, refer to the `IPython install
+page <http://ipython.org/install.html>`__.
+
+Kernels for other languages can be found in the `IPython wiki
+<https://github.com/ipython/ipython/wiki/IPython%20kernels%20for%20other%20languages>`_.
+They usually come with instruction what to run to make the kernel available in the notebook.
+
+
+.. _signing_notebooks:
+
+Signing Notebooks
+-----------------
+
+To prevent untrusted code from executing on users' behalf when notebooks open,
+we have added a signature to the notebook, stored in metadata.
+The notebook server verifies this signature when a notebook is opened.
+If the signature stored in the notebook metadata does not match,
+javascript and HTML output will not be displayed on load,
+and must be regenerated by re-executing the cells.
+
+Any notebook that you have executed yourself *in its entirety* will be considered trusted,
+and its HTML and javascript output will be displayed on load.
+
+If you need to see HTML or Javascript output without re-executing,
+you can explicitly trust notebooks, such as those shared with you,
+or those that you have written yourself prior to IPython 2.0,
+at the command-line with::
+
+    $ jupyter trust mynotebook.ipynb [other notebooks.ipynb]
+
+This just generates a new signature stored in each notebook.
+
+You can generate a new notebook signing key with::
+
+    $ jupyter trust --reset
+
+.. include:: links.txt
+
+Browser Compatibility
+---------------------
+
+The Jupyter Notebook is officially supported the latest stable version the following browsers:
+
+* Chrome
+* Safari
+* Firefox
+
+The is mainly due to the notebook's usage of WebSockets and the flexible box model.
+
+The following browsers are unsupported:
+
+* Safari < 5
+* Firefox < 6
+* Chrome < 13
+* Opera (any): CSS issues, but execution might work
+* Internet Explorer < 10
+* Internet Explorer ≥ 10 (same as Opera)
+
+Using Safari with HTTPS and an untrusted certificate is known to not work
+(websockets will fail).

+
+Running a notebook server
+=========================
+
+
+The :doc:`Jupyter notebook <notebook>` web application is based on a
+server-client structure.  The notebook server uses a :ref:`two-process kernel
+architecture <ipython:ipythonzmq>` based on ZeroMQ_, as well as Tornado_ for
+serving HTTP requests.
+
+.. note::
+   By default, a notebook server runs locally at 127.0.0.1:8888
+   and is accessible only from `localhost`. You may access the
+   notebook server from the browser using `http://127.0.0.1:8888`.
+
+This document describes how you can
+:ref:`secure a notebook server <notebook_server_security>` and how to
+:ref:`run it on a public interface <notebook_public_server>`.
+
+.. _ZeroMQ: http://zeromq.org
+
+.. _Tornado: http://www.tornadoweb.org
+
+
+.. _notebook_server_security:
+
+Securing a notebook server
+--------------------------
+
+You can protect your notebook server with a simple single password by
+configuring the :attr:`NotebookApp.password` setting in
+:file:`jupyter_notebook_config.py`.
+
+Prerequisite: A notebook configuration file
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Check to see if you have a notebook configuration file,
+:file:`jupyter_notebook_config.py`. The default location for this file
+is your Jupyter folder in your home directory, ``~/.jupyter``.
+
+If you don't already have one, create a config file for the notebook
+using the following command::
+
+  $ jupyter notebook --generate-config
+
+
+Preparing a hashed password
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can prepare a hashed password using the function
+:func:`notebook.auth.security.passwd`:
+
+.. sourcecode:: ipython
+
+    In [1]: from notebook.auth import passwd
+    In [2]: passwd()
+    Enter password:
+    Verify password:
+    Out[2]: 'sha1:67c9e60bb8b6:9ffede0825894254b2e042ea597d771089e11aed'
+
+.. caution::
+
+  :func:`~notebook.auth.security.passwd` when called with no arguments
+  will prompt you to enter and verify your password such as
+  in the above code snippet. Although the function can also
+  be passed a string as an argument such as ``passwd('mypassword')``, please
+  **do not** pass a string as an argument inside an IPython session, as it
+  will be saved in your input history.
+
+Adding hashed password to your notebook configuration file
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can then add the hashed password to your :file:`jupyter_notebook_config.py`.
+The default location for this file :file:`jupyter_notebook_config.py` is in
+your Jupyter folder in your home directory, ``~/.jupyter``, e.g.::
+
+    c.NotebookApp.password = u'sha1:67c9e60bb8b6:9ffede0825894254b2e042ea597d771089e11aed'
+
+Using SSL for encrypted communication
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+When using a password, it is a good idea to also use SSL with a web certificate,
+so that your hashed password is not sent unencrypted by your browser.
+
+.. important::
+   Web security is rapidly changing and evolving. We provide this document
+   as a convenience to the user, and recommend that the user keep current on
+   changes that may impact security, such as new releases of OpenSSL.
+   The Open Web Application Security Project (`OWASP`_) website is a good resource
+   on general security issues and web practices.
+
+You can start the notebook to communicate via a secure protocol mode by setting
+the ``certfile`` option to your self-signed certificate, i.e. ``mycert.pem``,
+with the command::
+
+    $ jupyter notebook --certfile=mycert.pem --keyfile mykey.key
+
+.. tip::
+
+    A self-signed certificate can be generated with ``openssl``.  For example,
+    the following command will create a certificate valid for 365 days with
+    both the key and certificate data written to the same file::
+
+        $ openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mykey.key -out mycert.pem
+
+When starting the notebook server, your browser may warn that your self-signed
+certificate is insecure or unrecognized.  If you wish to have a fully
+compliant self-signed certificate that will not raise warnings, it is possible
+(but rather involved) to create one, as explained in detail in `this tutorial`__.
+
+.. __: http://arstechnica.com/security/news/2009/12/how-to-get-set-with-a-secure-sertificate-for-free.ars
+
+.. TODO: Find an additional resource that walks the user through this two-process step by step.
+
+.. _OWASP: https://www.owasp.org
+
+
+.. _notebook_public_server:
+
+Running a public notebook server
+--------------------------------
+
+If you want to access your notebook server remotely via a web browser,
+you can do so by running a public notebook server. For optimal security
+when running a public notebook server, you should first secure the
+server with a password and SSL/HTTPS as described in
+:ref:`notebook_server_security`.
+
+Start by creating a certificate file and a hashed password, as explained in
+:ref:`notebook_server_security`.
+
+If you don't already have one, create a
+config file for the notebook using the following command line::
+
+  $ jupyter notebook --generate-config
+
+In the ``~/.jupyter`` directory, edit the notebook config file,
+``jupyter_notebook_config.py``.  By default, the notebook config file has
+all fields commented out. The minimum set of configuration options that
+you should to uncomment and edit in :file:``jupyter_notebook_config.py`` is the
+following::
+
+     # Set options for certfile, ip, password, and toggle off browser auto-opening
+     c.NotebookApp.certfile = u'/absolute/path/to/your/certificate/mycert.pem'
+     c.NotebookApp.keyfile = u'/absolute/path/to/your/certificate/mykey.key'
+     # Set ip to '*' to bind on all interfaces (ips) for the public server
+     c.NotebookApp.ip = '*'
+     c.NotebookApp.password = u'sha1:bcd259ccf...<your hashed password here>'
+     c.NotebookApp.open_browser = False
+
+     # It is a good idea to set a known, fixed port for server access
+     c.NotebookApp.port = 9999
+
+You can then start the notebook using the ``jupyter notebook`` command.
+
+.. important::
+
+    **Use 'https'.**
+    Keep in mind that when you enable SSL support, you must access the
+    notebook server over ``https://``, not over plain ``http://``.  The startup
+    message from the server prints a reminder in the console, but *it is easy
+    to overlook this detail and think the server is for some reason
+    non-responsive*.
+
+    **When using SSL, always access the notebook server with 'https://'.**
+
+You may now access the public server by pointing your browser to
+``https://your.host.com:9999`` where ``your.host.com`` is your public server's
+domain.
+
+Firewall Setup
+~~~~~~~~~~~~~~
+
+To function correctly, the firewall on the computer running the jupyter
+notebook server must be configured to allow connections from client
+machines on the access port ``c.NotebookApp.port`` set in
+:file:``jupyter_notebook_config.py`` port to allow connections to the
+web interface.  The firewall must also allow connections from
+127.0.0.1 (localhost) on ports from 49152 to 65535.
+These ports are used by the server to communicate with the notebook kernels.
+The kernel communication ports are chosen randomly by ZeroMQ, and may require
+multiple connections per kernel, so a large range of ports must be accessible.
+
+Running the notebook with a customized URL prefix
+-------------------------------------------------
+
+The notebook dashboard, which is the landing page with an overview
+of the notebooks in your working directory, is typically found and accessed
+at the default URL ``http://localhost:8888/``.
+
+If you prefer to customize the URL prefix for the notebook dashboard, you can
+do so through modifying ``jupyter_notebook_config.py``. For example, if you
+prefer that the notebook dashboard be located with a sub-directory that
+contains other ipython files, e.g. ``http://localhost:8888/ipython/``,
+you can do so with configuration options like the following (see above for
+instructions about modifying ``jupyter_notebook_config.py``)::
+
+    c.NotebookApp.base_url = '/ipython/'
+    c.NotebookApp.webapp_settings = {'static_url_prefix':'/ipython/static/'}
+
+Known issues
+------------
+
+Proxies
+~~~~~~~
+
+When behind a proxy, especially if your system or browser is set to autodetect
+the proxy, the notebook web application might fail to connect to the server's
+websockets, and present you with a warning at startup. In this case, you need
+to configure your system not to use the proxy for the server's address.
+
+For example, in Firefox, go to the Preferences panel, Advanced section,
+Network tab, click 'Settings...', and add the address of the notebook server
+to the 'No proxy for' field.
+
+Docker CMD
+~~~~~~~~~~
+
+Using ``jupyter notebook`` as a
+`Docker CMD <https://docs.docker.com/reference/builder/#cmd>`_ results in
+kernels repeatedly crashing, likely due to a lack of `PID reaping
+<https://blog.phusion.nl/2015/01/20/docker-and-the-pid-1-zombie-reaping-problem/>`_.
+To avoid this, use the `tini <https://github.com/krallin/tini>`_ ``init`` as your
+Dockerfile `ENTRYPOINT`::
+
+  # Add Tini. Tini operates as a process subreaper for jupyter. This prevents
+  # kernel crashes.
+  ENV TINI_VERSION v0.6.0
+  ADD https://github.com/krallin/tini/releases/download/${TINI_VERSION}/tini /usr/bin/tini
+  RUN chmod +x /usr/bin/tini
+  ENTRYPOINT ["/usr/bin/tini", "--"]
+
+  EXPOSE 8888
+  CMD ["jupyter", "notebook", "--port=8888", "--no-browser", "--ip=0.0.0.0"]

+
+Security in Jupyter notebooks
+=============================
+
+As Jupyter notebooks become more popular for sharing and collaboration,
+the potential for malicious people to attempt to exploit the notebook
+for their nefarious purposes increases. IPython 2.0 introduces a
+security model to prevent execution of untrusted code without explicit
+user input.
+
+The problem
+-----------
+
+The whole point of Jupyter is arbitrary code execution. We have no
+desire to limit what can be done with a notebook, which would negatively
+impact its utility.
+
+Unlike other programs, a Jupyter notebook document includes output.
+Unlike other documents, that output exists in a context that can execute
+code (via Javascript).
+
+The security problem we need to solve is that no code should execute
+just because a user has **opened** a notebook that **they did not
+write**. Like any other program, once a user decides to execute code in
+a notebook, it is considered trusted, and should be allowed to do
+anything.
+
+Our security model
+------------------
+
+-  Untrusted HTML is always sanitized
+-  Untrusted Javascript is never executed
+-  HTML and Javascript in Markdown cells are never trusted
+-  **Outputs** generated by the user are trusted
+-  Any other HTML or Javascript (in Markdown cells, output generated by
+   others) is never trusted
+-  The central question of trust is "Did the current user do this?"
+
+The details of trust
+--------------------
+
+Jupyter notebooks store a signature in metadata, which is used to answer
+the question "Did the current user do this?"
+
+This signature is a digest of the notebooks contents plus a secret key,
+known only to the user. The secret key is a user-only readable file in
+the Jupyter profile's security directory. By default, this is::
+
+    ~/.jupyter/profile_default/security/notebook_secret
+
+.. note::
+
+    The notebook secret being stored in the profile means that
+    loading a notebook in another profile results in it being untrusted,
+    unless you copy or symlink the notebook secret to share it across profiles.
+
+When a notebook is opened by a user, the server computes a signature
+with the user's key, and compares it with the signature stored in the
+notebook's metadata. If the signature matches, HTML and Javascript
+output in the notebook will be trusted at load, otherwise it will be
+untrusted.
+
+Any output generated during an interactive session is trusted.
+
+Updating trust
+**************
+
+A notebook's trust is updated when the notebook is saved. If there are
+any untrusted outputs still in the notebook, the notebook will not be
+trusted, and no signature will be stored. If all untrusted outputs have
+been removed (either via ``Clear Output`` or re-execution), then the
+notebook will become trusted.
+
+While trust is updated per output, this is only for the duration of a
+single session. A notebook file on disk is either trusted or not in its
+entirety.
+
+Explicit trust
+**************
+
+Sometimes re-executing a notebook to generate trusted output is not an
+option, either because dependencies are unavailable, or it would take a
+long time. Users can explicitly trust a notebook in two ways:
+
+-  At the command-line, with::
+
+    jupyter trust /path/to/notebook.ipynb
+
+-  After loading the untrusted notebook, with ``File / Trust Notebook``
+
+These two methods simply load the notebook, compute a new signature with
+the user's key, and then store the newly signed notebook.
+
+Reporting security issues
+-------------------------
+
+If you find a security vulnerability in Jupyter, either a failure of the
+code to properly implement the model described here, or a failure of the
+model itself, please report it to security@ipython.org.
+
+If you prefer to encrypt your security reports,
+you can use :download:`this PGP public key <ipython_security.asc>`.
+
+Affected use cases
+------------------
+
+Some use cases that work in Jupyter 1.0 will become less convenient in
+2.0 as a result of the security changes. We do our best to minimize
+these annoyance, but security is always at odds with convenience.
+
+Javascript and CSS in Markdown cells
+************************************
+
+While never officially supported, it had become common practice to put
+hidden Javascript or CSS styling in Markdown cells, so that they would
+not be visible on the page. Since Markdown cells are now sanitized (by
+`Google Caja <https://developers.google.com/caja>`__), all Javascript
+(including click event handlers, etc.) and CSS will be stripped.
+
+We plan to provide a mechanism for notebook themes, but in the meantime
+styling the notebook can only be done via either ``custom.css`` or CSS
+in HTML output. The latter only have an effect if the notebook is
+trusted, because otherwise the output will be sanitized just like
+Markdown.
+
+Collaboration
+*************
+
+When collaborating on a notebook, people probably want to see the
+outputs produced by their colleagues' most recent executions. Since each
+collaborator's key will differ, this will result in each share starting
+in an untrusted state. There are three basic approaches to this:
+
+-  re-run notebooks when you get them (not always viable)
+-  explicitly trust notebooks via ``jupyter trust`` or the notebook menu
+   (annoying, but easy)
+-  share a notebook secret, and use a Jupyter profile dedicated to the
+   collaboration while working on the project.
+
+Multiple profiles or machines
+*****************************
+
+Since the notebook secret is stored in a profile directory by default,
+opening a notebook with a different profile or on a different machine
+will result in a different key, and thus be untrusted. The only current
+way to address this is by sharing the notebook secret. This can be
+facilitated by setting the configurable:
+
+.. sourcecode:: python
+
+    c.NotebookApp.secret_file = "/path/to/notebook_secret"
+
+in each profile, and only sharing the secret once per machine.

+UI Components
+=============
+When opening bug reports or sending emails to the Jupyter mailing list, it is
+useful to know the names of different UI components so that other developers
+and users have an easier time helping you diagnose your problems. This section
+will familiarize you with the names of UI elements within the Notebook and the
+different Notebook modes.
+
+Notebook Dashboard
+-------------------
+
+When you launch ``jupyter notebook`` the first page that you encounter is the
+Notebook Dashboard.
+
+.. image:: /_static/images/jupyter-notebook-dashboard.png
+
+Notebook Editor
+---------------
+
+Once you've selected a Notebook to edit, the Notebook will open in the Notebook
+Editor.
+
+.. image:: /_static/images/jupyter-notebook-default.png
+
+Interactive User Interface Tour of the Notebook
+-----------------------------------------------
+
+If you would like to learn more about the specific elements within the Notebook
+Editor, you can go through the User Interface Tour by selecting Help in the
+menubar then selecting User Interface Tour.
+
+Edit Mode and Notebook Editor
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When a cell is in edit mode, the Cell Mode Indicator will change to reflect
+the cell's state. This state is indicated by a small pencil icon on the
+top right of the interface. When the cell is in command mode, there is no
+icon in that location.
+
+.. image:: /_static/images/jupyter-notebook-edit.png

+Now let's say that you've chosen to open a Markdown file instead of a Notebook
+file whilst in the Notebook Dashboard. If so, the file will be opened in the
+File Editor.

+        Not allowed with URLs or archives. Windows support for symlinks requires

+        Specify absolute path of nbextensions directory explicitly.
+    destination : str [optional]

+     * Splits a string into an array of strings using a regex or string

+     * backreferences are spliced into the result each time `separator` is
+     * matched. Fixes browser bugs compared to the native
+     * `String.prototype.split` and can be used reliably cross-browser.
+     * @param {String} str String to split.
+     * @param {RegExp} separator Regex to use for separating
+     *     the string.
+     * @param {Number} [limit] Maximum number of items to include in the result
+     *     array.
+     * @returns {Array} Array of substrings.
+     * @example
+     *
+     * // Basic use
+     * regex_split('a b c d', ' ');
+     * // -> ['a', 'b', 'c', 'd']
+     *
+     * // With limit
+     * regex_split('a b c d', ' ', 2);
+     * // -> ['a', 'b']
+     *
+     * // Backreferences in result array
+     * regex_split('..word1 word2..', /([a-z]+)(\d+)/i);

+/**
+ *
+ *
+ * Placeholder for custom user javascript
+ * mainly to be overridden in profile/static/custom/custom.js
+ * This will always be an empty file in IPython
+ *
+ * User could add any javascript in the `profile/static/custom/custom.js` file.
+ * It will be executed by the ipython notebook at load time.
+ *
+ * Same thing with `profile/static/custom/custom.css` to inject custom css into the notebook.
+ *
+ *
+ * The object available at load time depend on the version of IPython in use.
+ * there is no guaranties of API stability.
+ *
+ * The example below explain the principle, and might not be valid.
+ *
+ * Instances are created after the loading of this file and might need to be accessed using events:
+ *     define([
+ *        'base/js/namespace',
+ *        'base/js/events'
+ *     ], function(IPython, events) {
+ *         events.on("app_initialized.NotebookApp", function () {
+ *             IPython.keyboard_manager....
+ *         });
+ *     });
+ *
+ * __Example 1:__
+ *
+ * Create a custom button in toolbar that execute `%qtconsole` in kernel
+ * and hence open a qtconsole attached to the same kernel as the current notebook
+ *
+ *    define([
+ *        'base/js/namespace',
+ *        'base/js/events'
+ *    ], function(IPython, events) {
+ *        events.on('app_initialized.NotebookApp', function(){
+ *            IPython.toolbar.add_buttons_group([
+ *                {
+ *                    'label'   : 'run qtconsole',
+ *                    'icon'    : 'icon-terminal', // select your icon from http://fortawesome.github.io/Font-Awesome/icons
+ *                    'callback': function () {
+ *                        IPython.notebook.kernel.execute('%qtconsole')
+ *                    }
+ *                }
+ *                // add more button here if needed.
+ *                ]);
+ *        });
+ *    });
+ *
+ * __Example 2:__
+ *
+ * At the completion of the dashboard loading, load an unofficial javascript extension
+ * that is installed in profile/static/custom/
+ *
+ *    define([
+ *        'base/js/events'
+ *    ], function(events) {
+ *        events.on('app_initialized.DashboardApp', function(){
+ *            require(['custom/unofficial_extension.js'])
+ *        });
+ *    });
+ *
+ * __Example 3:__
+ *
+ *  Use `jQuery.getScript(url [, success(script, textStatus, jqXHR)] );`
+ *  to load custom script into the notebook.
+ *
+ *    // to load the metadata ui extension example.
+ *    $.getScript('/static/notebook/js/celltoolbarpresets/example.js');
+ *    // or
+ *    // to load the metadata ui extension to control slideshow mode / reveal js for nbconvert
+ *    $.getScript('/static/notebook/js/celltoolbarpresets/slideshow.js');
+ *
+ *
+ * @module IPython
+ * @namespace IPython
+ * @class customjs
+ * @static

+// * First pick a noun and a verb for the action. For example, if the action is "restart kernel," the verb is

+// * Omit terms like "selected" and "active" by default, so "delete-cell", rather than "delete-selected-cell".

+// * If an action has a secondary action, separate the secondary action with "-and-", so
+//   "restart-kernel-and-clear-output".
+// * Don't ever use before/after as they have a temporal connotation that is confusing when used in a spatial
+//   context.
+// * Use above/below or previous/next to indicate spacial and sequential relationships.
+// * For dialogs, use a verb that indicates what the dialog will accomplish, such as "confirm-restart-kernel".

+# IPython Notebook JavaScript Tests
+
+This directory includes regression tests for the web notebook. These tests
+depend on [CasperJS](http://casperjs.org/), which in turn requires a recent
+version of [PhantomJS](http://phantomjs.org/).
+
+The JavaScript tests are organized into subdirectories that match those in
+`static` (`base', `notebook`, `services`, `tree`, etc.).
+
+To run all of the JavaScript tests do:
+
+```
+iptest js
+```
+
+To run the JavaScript tests in a single subdirectory (`notebook` in this
+case) do:
+
+```
+iptest js/notebook
+```
+
+The file `util.js` contains utility functions for tests, including a path to
+a running notebook server on localhost (http://127.0.0.1) with the port
+number specified as a command line argument to the test suite. Port 8888 is
+used if `--port=` is not specified. When you run these tests using `iptest`
+you do not, however, have to start a notebook server yourself; that is done
+automatically.
