+Release
+=======
+
+Django MongoDB Backend uses GitHub Actions to publish new releases to PyPI. To
+publish a new release to PyPI:
+
+- Bump the version number in ``django_mongodb_backend/__init__.py``
+  according to :ref:`the supported versions policy
+  <supported-versions-policy>`.
+
+- Update the release notes in ``docs/releases/#.#.x.rst`` for the new version.
+
+- Run the ``Release`` workflow on GitHub Actions, optionally providing the new
+  (dev) version number as input. E.g. ``5.2.3.dev0`` for a new development
+  release after ``5.2.2``. (The workflow defaults to incrementing the
+  version automatically.)
+
+  - First run with ``Dry Run?`` selected and check test PyPI to ensure that
+    ``pip install`` works as expected.
+
+  - Then run without ``Dry Run?`` to publish the release to PyPI.
+
+- Announce the new release on the relevant communication channels.
