+Test selectors are originally a `leiningen` feature - see `lein help test` for some explanation.
 People use them to define subsets of tests usually run together for different purposes. For
 example you can mark some of your tests with the `^:smoke` metadata marker others with
 `^:integration`. This enables you to run these tests separately in your build pipeline.
-This feature in CIDER helps you to run these subsets in your development environment.
