Pull Request

1. Buat feature branch
2. Push ke remote
3. Buat Pull Request di GitHub/GitLab
4. Review dan merge

Troubleshooting

Undo last commit

# Soft reset (hapus commit tapi keep changes)
git reset --soft HEAD~1

# Hard reset (hapus commit dan discard changes)
git reset --hard HEAD~1

Stash Changes

# Simpan sementara
git stash

# Restore stash
git stash pop

Best Practices

1. Commit frequently - Small, frequent commits
2. Write good commit messages - Conventional Commits
3. Use .gitignore - Exclude unnecessary files
4. Pull before push - Avoid conflicts
5. Review changes before commit - git diff

Conventional Commits
