+*********************
+Accessing Plugin APIs
+*********************
+
+Each plugin object is wrapped by a public user API which enables interacting with the plugin from
+the notebook directly.  The plugin API object for each plugin is accessible through ``viz.plugins``.
+For example:
+
+.. code-block:: python
+
+  plugin = viz.plugins['Plot Options']
+  plugin.open_in_tray()
+  plugin.show('popout')
+
+When running in a notebook or lab environment, plugins provide API hints directly in the UI.  To enable these, toggle the ``<>`` button in the top of the plugin.
