 Here are the steps on how to make a new release.
 
-#. Create a ``release-VERSION`` branch from ``upstream/master``.
+#. Create a ``release-VERSION`` branch from ``origin/master``.
 #. Update ``CHANGELOG.rst``.
 #. Push a branch with the changes.
 #. Wait for all builds to pass and at least one approval.
-#. Push a tag ``VERSION`` to ``upstream``.
-#. Merge the PR.
+#. Start the ``deploy`` workflow:
+
+   .. code-block:: console
+
+        gh workflow run deploy.yml -R esss/pytest-regressions --ref release-VERSION --field version=VERSION
+
+   The PR will be automatically merged.
 
 After this, the package should be published directly to PyPI. After a few hours, it should be picked up by the conda-forge bot, where one of the maintainers need to merge it so the package can be published (another couple of hours after that).
