   3 Use [pre-commit](https://pre-commit.com/). Once you
   4 [have it installed](https://pre-commit.com/#install), add this to the
   5 `.pre-commit-config.yaml` in your repository:
   6
   7 ```yaml
   8 repos:
   9   - repo: https://github.com/psf/black
  10     rev: 22.3.0
  11     hooks:
  12       - id: black
  13         # It is recommended to specify the latest version of Python
  14         # supported by your project here, or alternatively use
  15         # pre-commit's default_language_version, see
  16         # https://pre-commit.com/#top_level-default_language_version
  17         language_version: python3.9
  18 ```

  20 Feel free to switch out the `rev` value to something else, like another
  21 [tag/version][black-tags] or even a specific commit. Although we discourage the use of
  22 branches or other mutable refs since the hook [won't auto update as you may
  23 expect][pre-commit-mutable-rev].
  24
  25 If you want support for Jupyter Notebooks as well, then replace `id: black` with
  26 `id: black-jupyter` (though note that it's only available from version `21.8b0`
  27 onwards).
