+#### File Overview
+All nightwatch.js tests are present in the `tests` directory. When writing 
+these tests, you may import needed functions from [fixtures.js](fixtures.js), which provides a convenient way to create resources needed for tests 
+via API, which might include organizations, users, and job templates.
+
+The `commands` directory provides extra functions for the client object in 
+nightwatch.js tests. For more information on these functions and how to 
+create your own, refer to the nightwatch.js documentation on custom commands.
