GIT QUEST

~ A REFRESHER IN 9 LEVELS ~

OLD COMMIT, THE SAGE

Welcome back, traveller. It's been a while since you last held a terminal. Your muscle memory has rusted, but it hasn't gone.

How to play:

Open a terminal (macOS/Linux Terminal, or Git Bash on Windows) and run each objective yourself. Type the commands out rather than pasting where you can, since typing is how you'll remember them.
Tick each objective when it's done. Clearing a level unlocks the next one.
Stuck? Open "What you should see" under each step.
Everything happens in a throwaway folder called git-quest. Nothing touches your real projects, and you don't need a GitHub account (Level 7 fakes a server on your own machine).

Your progress is saved in this browser.

★ QUEST COMPLETE ★

You've earned the title GIT WIZARD. You can now commit, branch, merge, resolve conflicts, rewrite history, rescue lost work and collaborate.

New Game+ ideas:

Replay the whole quest tomorrow without opening the hints.
Push git-quest to a real GitHub repo and open a pull request against yourself.
Try git bisect to hunt down which commit broke something.
Learn git cherry-pick and git worktree.

Tip: run git status whenever you're lost. It's the minimap of Git.
