I use Git every day. Will I learn anything?

Probably. Levels 4 to 9 cover what daily users often skip: the reflog, interactive rebase and range-diff, how objects and refs work, rulesets and signed releases, bisect, worktrees, Git with coding agents, and GitOps. The predict challenges show quickly where your picture of Git is off.

Do I need GitHub or a cloud account?

A free GitHub account from Level 3, where you open real pull requests. Level 9 runs Kubernetes and Argo CD on your own computer with Docker, kind and kubectl; no cloud account is needed.

Which Git version do I need?

The screens were made with Git 2.55, and the lessons work on recent versions. The few newer features, such as git history and config-based hooks, say which version they need.

Do I get a certificate?

Yes. Read every lesson and pass all 10 projects, and you can claim a Preporato certificate of completion with your name on it, at a link anyone can open to check it.

Outcomes

What you'll have built

Real artifacts from the projects, kept in your own setup after the course.

git log --graph shows a merge commit on main joining the brownie commit and the chai commit

After Level 2

Your first clean repositories

A friend's website committed in small, readable steps, and two teammates' branches merged with a real conflict resolved by hand.

git tag -v shows the tag object and Good git signature for sam@example.com

After Level 7

A team-ready repository

Code owners, a pull request template, a commit-msg hook enforcing Conventional Commits, signed commits and a signed release tag, all checked.

f03a388 is the first bad commit: Tidy the price list by Priya Shah

After Level 8

A bug found by bisect

A test script git bisect can trust, the culprit found among 60 commits despite three that don't build, and the fix as a clean revert.

Argo CD's applications page shows cafe-production and cafe-staging, each Healthy and Synced

After Level 9

A release shipped with GitOps

A price change promoted from staging to production by Argo CD and rolled back with a revert, with every step in Git's history and Argo CD's.

real screens

Real screens, numbered

The walkthroughs show what Git actually printed, captured by running the commands, with numbered callouts on the lines that matter. Your practice folder starts with the same history, so the commit IDs on your screen match the lesson.

Predict first, then check

Predict challenges ask what Git will do before you run it: what goes in the commit, what a merge or a rebase does, which commit bisect blames. Then you run it in your own terminal and see.

Graded from your own repository

Each level ends with a project and a self-check that reads your actual repository: commits, branches, signatures, even Argo CD’s deployment history. Read every lesson and pass all ten projects for a certificate of completion.

After the course

What you can do, and what you'll have used

You'll be able to

Make, read and undo commits with confidence, knowing exactly what the working tree, staging area and repository hold
Branch, merge and resolve conflicts, then collaborate on GitHub with fetch, pull, push, forks and pull requests
Recover from mistakes with restore, reset, revert, the reflog and stash, without losing work
Keep a clean history with interactive rebase, fixups, stacked branches and safe force-pushes
Explain how Git stores everything as objects and refs, and build a commit with plumbing commands alone
Set up a repository for a team: code owners, pull request templates, rulesets, Conventional Commits, signed commits and releases
Find bugs with bisect, trace code with blame and the pickaxe, and work in parallel with worktrees, including alongside coding agents
Deploy, promote and roll back with GitOps, using Argo CD on a local Kubernetes cluster

FAQ

Questions, answered

Yes. Level 1 starts with installing Git and making your first commit, and the walkthroughs show every screen you should see. You need a terminal: Terminal on a Mac, any Linux shell, or Git Bash on Windows.

About this course. Git is the tool almost every developer uses daily and few fully understand. This course teaches it hands-on: you run every command yourself in a practice folder whose repositories have the same history as the lessons' screens, so your commit IDs match until you make commits of your own. The walkthroughs show the real terminal output with numbered callouts, predict challenges check that you know what Git will do before it does it, and every level ends with a project and a self-check that reads your repository. You start with your first commit and finish running GitOps: Argo CD deploying, promoting and rolling back a website on a Kubernetes cluster on your own computer.
