+### News / Changelog Requirement
+
+`Black` has CI that will check for an entry corresponding to your PR in `CHANGES.md`. If

+maintainer can add a `skip news` label to make the CI pass. Otherwise, please ensure you
+have a line in the following format:

+```md

+```

+is not perfect but saves a lot of release overhead as now the releaser does not need to
+go back and workout what to add to the `CHANGES.md` for each release.
+
+### Docs Testing
+
+If you make changes to docs, you can test they still build locally too.

+```console
+$ pip install -r docs/requirements.txt
+$ pip install [-e] .[d]
+$ sphinx-build -a -b html -W docs/ docs/_build/
