# Version control integration
Use [pre-commit](https://pre-commit.com/). Once you
[have it installed](https://pre-commit.com/#install), add this to the
`.pre-commit-config.yaml` in your repository:
```yaml
repos:
# Using this mirror lets us use mypyc-compiled black, which is about 2x faster
- repo: https://github.com/psf/black-pre-commit-mirror
rev: 25.12.0
hooks:
- id: black
# It is recommended to specify the latest version of Python
# supported by your project here, or alternatively use
# pre-commit's default_language_version, see
# https://pre-commit.com/#top_level-default_language_version
language_version: python3.11
```
Feel free to switch out the `rev` value to a different version of Black.
Note if you'd like to use a specific commit in `rev`, you'll need to swap the repo
specified from the mirror to https://github.com/psf/black. We discourage the use of
branches or other mutable refs since the hook [won't auto update as you may
expect][pre-commit-mutable-rev].
## Jupyter Notebooks
There is an alternate hook `black-jupyter` that expands the targets of `black` to
include Jupyter Notebooks. To use this hook, simply replace the hook's `id: black` with
`id: black-jupyter` in the `.pre-commit-config.yaml`:
```yaml
repos:
# Using this mirror lets us use mypyc-compiled black, which is about 2x faster
- repo: https://github.com/psf/black-pre-commit-mirror
rev: 25.12.0
hooks:
- id: black-jupyter
# It is recommended to specify the latest version of Python
# supported by your project here, or alternatively use
# pre-commit's default_language_version, see
# https://pre-commit.com/#top_level-default_language_version
language_version: python3.11
```
```{note}
The `black-jupyter` hook became available in version 21.8b0.
