The Three Trees

Working Directory → Staging Area → Repository.

Phase 3Rewriting History — the commands that trip people up

Replaying commits onto a new base, new hashes.

One Commit at a Time

Copy a single commit onto your current branch.

reset vs revert

Undoing Commits

soft/mixed/hard reset, compared with a safe revert.

Phase 4Collaboration

Shelve uncommitted changes, switch branches, pop back.

Talking to Origin

Remote tracking refs, and why pushes get rejected.

Marking Releases

Lightweight vs annotated tags, checking one out.
