 It's possible to add a prelude to the release notes for a particular release
 using a ``prelude`` section in a ``reno`` note.
 
+Creating a release candidate
+============================
+
+Prior to cutting a stable branch, the ``master`` branch should be tagged as a
+release candidate.  This allows the ``reno`` tool to determine where to stop
+searching for release notes for the next release.  The tag should take the
+following form: ``<release tag>.0rc$n``, where ``$n`` is the release candidate
+number.
+
+The ``tools/release.sh`` script in the ``kayobe`` repository can be used to tag
+a release and push it to Gerrit. For example, to tag and release the ``kayobe``
+deliverable release candidate ``4.0.0.0rc1`` in the Queens series from the base
+of the ``stable/queens`` branch:
+
+.. code-block:: console
+
