+### Pre-commit hooks
+
+> [!IMPORTANT]
+> Playwright tests are run on pre-commit hooks and will fail if Playwright is not installed. See [running the tests](#running-the-tests) for info on how to set up Playwright
+
+Pre-commit hooks are managed by [Husky](https://typicode.github.io/husky/get-started.html) and will be run whenever you make a commit. If they fail then the commit will be aborted and you will see an error.
+
+To run pre-commit hooks without committing, stage all your changes and then execute the `.husky/pre-commit` file.
+
+To commit but skip pre-commit hooks, run `git commit -m "my amazing commit message" --no-verify`
