- The Conventional Commits format (feat:, fix:, docs:, etc.)
- Writing a good commit subject line
- Adding a longer commit body when needed
- Avoiding unrelated changes in one commit
- Reviewing your diff before committing
- What makes a commit 'atomic'
- Why commit history quality matters months later
