+## Code Style
+
+This project uses [Laravel Pint](https://laravel.com/docs/pint) for code styling. Pint is an opinionated PHP code style fixer for minimalists, built on top of PHP-CS-Fixer.
+
+To automatically fix code style issues, run:
+
+```bash
+composer pint
+```
+
+To check for code style issues without fixing them:
+
+```bash
+composer pint-test
+```
+
+The code style configuration can be found in `pint.json`.
