Learn git by using it

Each Lesson explains one idea with an animated Explainer, then gives you Challenges to solve by typing git commands into a simulated Terminal in your browser. A Live Graph of your repository updates with every command.

Start with How this works

How it works

1. Watch the idea

   An Explainer shows what a command does to the repository, one step at a time, at your pace.

2. Type the commands

   The Terminal simulates git, so there is nothing to install and nothing on your machine to break. Hints are free when you're stuck.

3. Reach the Goal State

   A Challenge is done when the repository looks right, whichever commands got it there. Finishing within Par earns bonus XP.
