Understand Git: working files, staging, and commits
See how working files, the staging area, and committed history differ in a small Git repository.
Six lessons · your first Git workflow
Learn Git, one checkpoint at a time.
Start with the snapshot model, then practice commits, review, branches, and sharing. Each lesson creates its own sandbox, so you can restart or jump ahead without losing earlier work.
Create a Git repository and your first commit
Initialize a local repository, configure its author identity, and record a first commit without a hosting account.
Read Git status, diffs, and commit history
Identify staged, unstaged, and untracked changes and inspect the exact snapshot that a commit records.
Create Git branches and merge a feature
Practice a local feature branch and a deliberate merge, then understand the resulting commit graph.
Understand Git remotes: clone, fetch, pull, and push
Practice sharing commits with a local bare remote and two clones, without credentials or a hosting account.
A daily Git workflow: review, verify, commit, and sync
Practice a repeatable Git workflow that separates reviewing changes, checking behavior, and publishing commits.
