   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: 21.7b0
  11     hooks:
  12       - id: black
  13         language_version: python3 # Should be a command that runs python3.6+
  14 ```
  15
  16 Feel free to switch out the `rev` value to something else, like another
  17 [tag/version][black-tags] or even a specific commit. Although we discourage the use of
  18 branches or other mutable refs since the hook [won't auto update as you may
  19 expect][pre-commit-mutable-rev].
  20
  21 If you want support for Jupyter Notebooks as well, then replace `id: black` with
  22 `id: black-jupyter` (though note that it's only available from version `21.8b0`
  23 onwards).
