 ## Checklist before merging
-- [ ] If it's a frontend feature, I have ran prettier `cd frontend; npm run format`. If it's a mobile app feature I ran `cd mobile; npm run format`.
+- [ ] Install [pre-commit](https://pre-commit.com/#installation) and initialize it: `pip install pre-commit`, then `pre-commit install`. Pre-commit installs git hooks that automatically check the codebase. If pre-commit fails when you commit your changes, please fix the problems it points out.
 - [ ] If I added new phrases to the user interface, I have ran prettier `cd frontend/static/locales; python collect_phrases.py` to collect them for translation.
