 ## Testing and Development
 
 If you want to develop new content for this collection or improve what's already here, the easiest way to work on the collection is to clone it into one of the configured [`COLLECTIONS_PATHS`](https://docs.ansible.com/ansible/latest/reference_appendices/config.html#collections-paths), and work on it there.
