+### Git hooks
+
+A pre-commit hook is provided that runs `mix format --check-formatted` and `mix test` before each commit. Install it with `mix hooks.install` or manually copy `scripts/pre-commit` to `.git/hooks/pre-commit`.

 - **Prefer small, focused commits** - each commit should represent a single logical change
