Full contents

Everything Git and GitHub have to offer, in the order that makes each next step feel earned.

PART I

Foundations

Understand what Git is, why it exists, and how it thinks — before you type a single command in anger.

The problem before the tool

Feel why version control had to be invented.

Installing Git & first commit

init, add, commit, config, .gitignore.

Snapshots, hashes, objects

How Git actually stores your work.

The three areas

Working directory · staging · repository.

Reading history

log, diff, blame, show, reflog.

Undoing things

restore, reset, revert, amend — safely.

PART II

Branching

Try ideas without risk. The most powerful concept in Git, plus every advanced tool built on top of it.

Branches

Parallel timelines, the traveler's world.

Merging & conflicts

Fast-forward, 3-way, conflict resolution.

Rebasing

When to use, when NEVER to, interactive mode.

Cherry-pick, stash, tags, bisect

The specialised tools you'll reach for someday.

PART III

GitHub & Collaboration

Move from local repositories to shared code hosted online, and understand how teams review each other's work.

Remotes, forks, upstream

clone, fetch, pull, push · fork sync flow.

Authentication

SSH keys, HTTPS + PAT, signed commits.

Pull requests end-to-end

Open, review, request changes, suggestions, merge.

Merge strategies deep-dive

Squash vs merge commit vs rebase-merge · why Accelerate picked what.

Branch protection & CODEOWNERS

Required reviews, status checks, forced signatures.

PART IV

GitHub as a platform

The features on top of Git that make GitHub GitHub — issues, Actions, Pages, releases, security scans.

Issues, labels, projects

Milestones, discussions, cross-references, "closes #".

GitHub Actions

Workflows, jobs, steps, matrix builds.

CI/CD in practice

Tests on PR · deploy on release · secrets · OIDC.

Pages & releases

Publishing sites, custom domains, tagged releases.

Security tooling

Dependabot, secret scanning, push protection, CodeQL.

PART V

Accelerate

How our organisation is put together, and how you take your first real contribution from idea to merged PR.

How Accelerate works

Org structure · teams · Constitution ties · Discord bridge.

Your first contribution

End-to-end: pick an issue, fork, branch, PR, merged.
