+Storage Backends
+================
+
+To create a custom storage backend you will need to subclass the
+:class:`StorageBackend` class.  Then create an instance of the new class and
+pass that as the `storage` keyword argument when you create the
+:class:`~.WebSupport` object::
+
+   support = WebSupport(srcdir=srcdir,
+                        builddir=builddir,
+                        storage=MyStorage())
+
+For more information about creating a custom storage backend, please see the
+documentation of the :class:`StorageBackend` class below.
+
+.. class:: StorageBackend
+
+   Defines an interface for storage backends.
+
+.. versionchanged:: 1.6
+
+   StorageBackend class is moved to sphinxcontrib.websupport.storage from
+   sphinx.websupport.storage.
