 When you commit with Commitizen, you'll be prompted to fill out any required commit fields at commit time. No more waiting until later for a git commit hook to run and reject your commit (though [that](https://github.com/kentcdodds/validate-commit-msg) can still be helpful). No more digging through [CONTRIBUTING.md](CONTRIBUTING.md) to find what the preferred format is. Get instant feedback on your commit message formatting and be prompted for required fields.
