+Execution of checkstyle.py can be automated through git commit hooks. Example
+of pre-commit and post-commit hooks are available in `utils/hooks/pre-commit`
+and `utils/hooks/post-commit`. You can install either hook by copying it to
+`.git/hooks/`. The post-commit hook is easier to start with as it will only flag
+potential issues after committing, while the pre-commit hook will abort the
+commit if issues are detected and requires usage of `git commit --no-verify` to
+ignore false positives.

 Happy hacking, libcamera awaits your patches!
