+# Install pre-commit hooks
+
+As a contributor to the project, you can use pre-commit hooks to perform some
+verifications before committing your work. This document describes how to
+install them.
+
+The use of these pre-commit hooks is not required, but will allow you to check
+things that will otherwise fail later when the GitHub Actions are run.
+
+## Installation instructions
+
+1. Install a recent version of Python 3.
+2. Install pre-commit using pip (see also <https://pre-commit.com/#install>):
+   ```
+   pip install pre-commit  
+   ```
+3. From the root of the Jaybird repository, run:
+   ```
+   pre-commit install
+   ```
+
+Now the pre-commit hooks are installed and will run before commit.
+
+## Available pre-commit hooks
+
+Jaybird currently defines the following pre-commit hooks:
+
+### reuse
+
+Checks if appropriate copyright and license information is present, verifies
+compliance with the REUSE specification.
+
+If you want to be able to run `reuse` manually, follow the installation instructions on <https://github.com/fsfe/reuse-tool?tab=readme-ov-file#install>.
+
+A manual compliance check can then be run with:
+
+```
+reuse lint
+```
