The Git Roadmap

Every phase is labelled by level so you can start where you are. Each topic opens with a real-life analogy, then commands and code you run yourself, then questions with reveal answers. Progress is saved as you go.

The full curriculum

Level
Phase 0

The Git Mindset

Beginner ~69 min0/5 · 0%

Why version control exists, the three-tree model that everything else builds on, and your first real repository.

Phase 1

Everyday Git

Beginner ~56 min0/4 · 0%

Stage precisely, read history fluently, and undo mistakes with the right command instead of the scary one.

Phase 2

Branching & Merging

Intermediate ~57 min0/4 · 0%

Branches are just movable pointers — understanding that one fact demystifies merging, conflicts, and the rebase-vs-merge debate entirely.

Phase 3

Working with Remotes

Intermediate ~56 min0/4 · 0%

A remote is just another copy of the repository with a name — clone, fetch, pull, and push are how you stay in sync with it.

Phase 4

Collaboration Workflows

Intermediate ~55 min0/4 · 0%

The commands are the easy part — branching strategy, review etiquette, and real conflict resolution are what actually make a team's Git usage work.

Phase 5

Rewriting History Safely

Advanced ~56 min0/4 · 0%

Amend, cherry-pick, reflog, and force-push — the tools that touch history directly, and the exact rules that keep them safe instead of catastrophic.

Phase 6

Advanced Git Tools

Advanced ~70 min0/5 · 0%

Stash, bisect, tags, submodules, and worktrees — the specialized tools that solve specific, real problems once you know they exist.

Phase 7

Git in Production

Advanced ~72 min0/5 · 0%

Line endings, commit messages, CI, and disaster recovery — the operational realities of Git that matter once real teams and real deployments are involved.

Phase 8

Git Internals & Git at Scale

Advanced ~28 min0/4 · 0%

Open the .git directory: blobs, trees, commits, refs, and packfiles; keep repositories healthy; clone and work fast in huge repos with shallow, partial, and sparse checkouts; and protect main with rulesets, CODEOWNERS, and merge queues.
