+==========================================
+Neutron Tempest Plugin Release Notes Howto
+==========================================
+
+Release notes are a new feature for documenting new features in
+OpenStack projects. Background on the process, tooling, and
+methodology is documented in a `mailing list post by Doug Hellmann <http://lists.openstack.org/pipermail/openstack-dev/2015-November/078301.html>`_.
+
+Writing release notes
+---------------------
+
+For information on how to create release notes, please consult the
+`reno documentation <https://docs.openstack.org/reno/latest/user/usage.html>`__.
+
+Please keep the following in your mind when you write release notes.
+
+* **Avoid using "prelude" section** for individual release notes.
+  "prelude" section is for general comments about the release.
+* **Use one entry per section** (like "feature" or "upgrade").
+  All entries which belong to a same release will be merged and rendered,
+  so there is less meaning to use multiple entries by a single topic.
+
+Maintaining release notes
+-------------------------
+
+.. warning::
+
+   Avoid modifying an existing release note file even though it is related
+   to your change. If you modify a release note file of a past release,
+   the whole content will be shown in a latest release. The only allowed
+   case is to update a release note in a same release.
+
+   If you need to update a release note of a past release,
+   edit a corresponding release note file in a stable branch directly.
