+## ./UnitTests
+
+This folder contains the unit tests for Terminal.Gui that can not be run in parallel. This is because they
+depend on `Application` or other class that use static state or `ConfigurationManager`.
+
+We should be striving to move as many tests as possible to the `./UnitTestsParallelizable` folder.

+## ./UnitTestsParallelizable

+See the [Testing wiki](https://github.com/gui-cs/Terminal.Gui/wiki/Testing) for details on how to add more tests.
