     dependencies:
        - { role: '/path/to/common/roles/foo', x: 1 }
 
+Role dependencies can also be installed from source control repos or tar files, using a comma separated format of path, an optional version (tag, commit, branch etc) and optional friendly role name (an attempt is made to derive a role name from the repo name or archive filename)::

 Roles dependencies are always executed before the role that includes them, and are recursive. By default, 
 roles can also only be added as a dependency once - if another role also lists it as a dependency it will
 not be run again. This behavior can be overridden by adding `allow_duplicates: yes` to the `meta/main.yml` file.
