Learn Git by doing

A free, interactive Git tutorial. Join a small team, run real git commands in your browser, and learn commits, branches, merges, conflicts, pull requests, stash, reset and more.

The tutorial

1. Get the code: Clone a real project with git clone and read its history with git log.
2. Save a change: Edit a file, check it with git status and git diff, stage it with git add, commit it and push it.
3. Branches: Create a branch with git switch -c, work on it, switch back, and merge it with a fast-forward.
4. Teamwork: Fetch and pull your teammates' commits, get a push rejected, and fix it with a merge commit.
5. Conflicts: Change the same line as a teammate, read the conflict markers, resolve them, and finish the merge.
6. Pull requests: Review and merge a teammate's pull request, push your own branch with -u, open a PR, and clean up.
7. Undo mistakes: Unstage and discard changes with git restore, and undo a pushed commit safely with git revert.
8. Stash: Put unfinished work aside with git stash to make an urgent fix, then bring it back with git stash pop.
9. Fix your commits: Fix a commit with --amend, undo it with git reset --soft and --hard, and recover it with git reflog.

Questions

Is this Git tutorial free?

Yes. It's free, runs entirely in your browser, and needs no account or install.

Do I need to install Git?

No. The tutorial simulates a real Git repository, a terminal and GitHub in your browser. The commands are exactly the ones you'll use with real Git.

How is this different from other Git tutorials?

You work on a real-looking project with simulated teammates who push commits, open pull requests and create conflicts, so you practice collaboration, not just commands in isolation.

What will I learn?

Cloning, committing, the staging area, branches, merging, fetch and pull, resolving merge conflicts, pull requests, undoing mistakes with restore and revert, git stash, commit --amend, reset and reflog.

How long does it take?

About an hour for all nine chapters. Your progress is saved, so you can stop and come back anytime.
