Git

The Git textbook, chapter by chapter

Git from scratch: version control for beginners

Eight chapters and a final project. The first three hand you the working cycle: a repository, the three areas, a commit. Then come undoing changes, branches and merges, GitHub and working together, team habits, and a first-aid kit for when something goes wrong. The book closes with a project that runs through all of it: your own repository on GitHub, from git init to a pull request. No programming experience needed, the chapters run in order, and each one ends with exercises and a short recap.
