Master Git by
Actually Using It

Git is the version control tool that runs on your computer and tracks changes to your files. GitHub is an online platform that hosts Git repositories so you can back up your code, share it, and collaborate through pull requests and code reviews. GitMission teaches both: Missions 1 to 6 cover Git itself, and Missions 7 and 8 cover GitHub and team collaboration.

Across 8 missions you'll learn how to initialize a repository, check status, stage files, make commits with good commit messages, view history and changes, and use .gitignore. You'll also learn how to undo changes (unstage, amend, reset, revert), create and merge branches, and use stash, rebase, cherry-pick, bisect, and aliases. The GitHub missions then cover SSH keys, push, pull, clone, forks, pull requests, and code reviews.

The 8 missions add up to roughly 7 hours of hands-on practice, and each mission takes about 10 to 75 minutes. The core Git essentials (init, add, commit, history, undoing changes, and branching) are covered in the first five missions, which take about 3.5 hours. You can work through them at your own pace.

Git has a reputation for being confusing, mostly because people try to memorize commands without understanding what is happening behind the scenes. Practicing in realistic scenarios with immediate feedback makes ideas like staging, branching, and merging click much faster than reading documentation. Because GitMission is a safe sandbox, you can make mistakes without any fear of breaking a real project.

Yes. GitMission is built around real-world problems: untangling merge conflicts, fixing a messy rebase, undoing commits with reset and revert, recovering lost work, and tracking down bugs with git bisect. These are the parts of Git that scare most developers, and a sandbox is the safest place to practice them.

Yes. The GitHub Basics mission covers creating a repository, setting up an SSH key, pushing, cloning, and pulling changes, plus writing a README.md and a GitHub profile README. The Advanced GitHub and Collaboration mission then covers remote branches, forking repositories, pull requests, and code reviews, which is the workflow used by open-source projects and professional teams.

It is a sandboxed terminal that runs inside your browser, where you type real Git commands and see the results immediately. GitMission validates each step so you know right away whether your command did what the mission needed. Nothing touches the files on your computer, so you can experiment freely.

Each mission is a small project scenario. Simulated AI teammates set the context, assign tasks, and put you in situations like reviewing a pull request or resolving a conflict. You practice Git the way it is actually used on an engineering team instead of learning commands in isolation.

No. You can open your first mission without logging in, and no credit card is required. Just open your browser, join the team, and start learning Git.

Yes. Missions 4 to 8 go well beyond the basics, covering undoing changes, branching and merging, stash, rebase, cherry-pick, bisect, remote branches, forking, and pull requests. If you are comfortable with add and commit but nervous about rebase or merge conflicts, those are the missions to focus on.

Git and GitHub are expected skills in almost every software development role, and interviewers often ask about branching, merging, rebasing, and resolving conflicts. Practicing those workflows hands-on gives you answers based on real experience instead of memorized definitions.
