 ## Marking extra actions for routing
 
-If you have ad-hoc methods that should be routable, you can mark them as such with the `@action` decorator. Like regular actions, extra actions may be intended for either a list of objects, or a single instance. To indicate this, set the `detail` argument to `True` or `False`. The router will configure its URL patterns accordingly. e.g., the `DefaultRouter` will configure detail actions to contain `pk` in their URL patterns.

-Extra actions can be mapped to different `ViewSet` methods. For example, the above password set/unset methods could be consolidated into a single route. Note that additional mappings do not accept arguments.
