+Branching
+=========
+
+Stable branches are created when features are frozen for next release. According to
+`OPNFV release milestone description`_, stable branch window is open on MS6 and closed on MS7.
+
+#. Contact gerrit admin <opnfv-helpdesk@rt.linuxfoundation.org> to create branch for project.
+#. Setup `qtip jobs`_ and `docker jobs`_ for stable branch in releng
+#. Follow `instructions for stable branch`_.
+
+NOTE: we do **NOT** create branches for feature development as in the popular `GitHub Flow`_
