# 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:

```

Feel free to switch out the rev value to something else, like another [tag/version][black-tags] or even a specific commit. Although 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:

```

`{note} The `black-jupyter` hook became available in version 21.8b0. `
