+Cleanup
+=======
+
+This is the cog guide for the cleanup cog. You will
+find detailed docs about usage and commands.
+
+``[p]`` is considered as your prefix.
+
+.. note:: To use this cog, load it by typing this::

+.. _cleanup-usage:
+
+-----
+Usage
+-----
+
+This cog contains commands used for "cleaning up" (deleting) messages.
+
+This is designed as a moderator tool and offers many convenient use cases.
+All cleanup commands only apply to the channel the command is executed in.
+
+Messages older than two weeks cannot be mass deleted.
+This is a limitation of the API.
