+Storage Server Plugin Configuration
+===================================
+
+In addition to the built-in storage server,
+it is also possible to load and configure storage server plugins into Tahoe-LAFS.
+
+Plugins to load are specified in the ``[storage]`` section.
+
+``plugins = (string, optional)``
+
+    This gives a comma-separated list of plugin names.
+    Plugins named here will be loaded and offered to clients.
+    The default is for no such plugins to be loaded.
+
+Each plugin can also be configured in a dedicated section.
+The section for each plugin is named after the plugin itself::
+
+  [storageserver.plugins.<plugin name>]
+
+For example,
+the configuration section for a plugin named ``acme-foo-v1`` is ``[storageserver.plugins.acme-foo-v1]``.
+
+The contents of such sections are defined by the plugins themselves.
+Refer to the documentation provided with those plugins.
