Foundations

Git & GitHub

Version control taught through a project rather than as a list of commands. You take something you built earlier and make it a professional repository, with a real git running in the browser so every command is practiced rather than described.

The course project

Professional Repository

Repository, README, screenshots, documentation, real commit history, branches, issues, a pull request, and a deployment.

Each module ends with a practice test, a graded build, and a step of the course project.

Part I: Tracking Work

Why Version Control Exists

Not backup. A record of decisions you can read, search, and undo.

What Belongs in a Repository

The gitignore file, and the mistake that is genuinely hard to undo.

Reading History

A repository you cannot read is a repository you cannot trust.

Part II: Parallel Work

Branching

A safe place to try something. This is what makes git worth learning.

Remotes and GitHub

Your history, somewhere other than your laptop.

Part III: Working With Others

Pull Requests and Collaboration

How changes get proposed, discussed, and accepted, on every team you will ever join.
