 The EXAMPLES section, just like the documentation section, is required in
 all module pull requests for new modules.
 
+The RETURN section documents what the module returns. For each value returned,
+provide a ``description``, in what circumstances the value is ``returned``,
+the ``type`` of the value and a ``sample``.  For example, from

 * Try to normalize parameters with other modules, you can have aliases for when user is more familiar with underlying API name for the option

 * Avoid '`action`/`command`', they are imperative and not declarative, there are other ways to express the same thing
-* Sometimes you want to split the module, specially if you are adding a list/info state, you want a _facts version
