+### News / Changelog Requirement
+
+`Black` has CI that will check for an entry corresponding to your PR in `CHANGES.md`. If
+you feel this PR not require a changelog entry please state that in a comment and a
+maintainer can add a `skip news` label to make the CI pass. Otherwise, please ensure you
+have a line in the following format:
+
+```md
+- `Black` is now more awesome (#X)
+```
+
+To workout X, please use
+[Next PR Number](https://ichard26.github.io/next-pr-number/?owner=psf&name=black). This
+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.
+
+### Style Changes
+
+If a change would affect the advertised code style, please modify the documentation (The
+_Black_ code style) to reflect that change. Patches that fix unintended bugs in
+formatting don't need to be mentioned separately though.
+
+### 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/
