What is Git?

Git is a tool that remembers every version of your project. You can look back at old versions, try ideas safely on a branch, and share work with other people.

Think of it as a save game for code: each save is called a commit, and it comes with a message that says what changed.

The practice terminal on every page understands the most useful Git commands. Nothing leaves your browser. Check that Git is ready:

Four words you will meet again and again:

• Repository (repo): a project folder that Git is tracking.
• Commit: one saved snapshot of the project.
• Branch: a separate line of work.
• Remote: a copy of the repo kept somewhere else, such as GitHub.
