GitHub Collaboration Through Git History
Created by James Stothard
Build a working mental model of Git history, commits, and refs so you can predict what common commands actually change. You’ll learn the correct local workflow entry (clone vs init), how synchronization works with remote-tracking branches, and how branches, PRs, and merge methods shape collaborative history.
Requirements
- Basic command-line navigation (cd, ls, running commands)
- Ability to edit files locally in a project folder
- Basic awareness of a branch name like main
- Knowing what a GitHub repository URL is
What you'll learn
- Explain what data and authority live locally in Git versus on GitHub, and predict which operations affect each.
- Interpret Git history as a commit graph, using branches and HEAD as pointers to reason about state changes.
- Create reviewable, atomic commits by using staging intentionally and writing messages that preserve intent.
Learning path
6 modules • Each builds on the previous one
1
Git vs GitHub Responsibilities
Distinguish Git as the local version-control engine from GitHub as the collaboration and policy layer, and learn what each one is authoritative about during day-to-day work.
1 video8 min
2
Version Control Mechanics Deep Dive
Build a mental model of Git as a content-addressed history graph, including how snapshots, parents, branches, and pointers create the ability to compare and revert safely.
1 video6 min
3
Anatomy of a Commit
Understand what a commit contains (snapshot identity, parents, metadata, message) and how the staging area controls exactly what goes into each snapshot.
1 video7 min
4
Cloning, Initializing, and Remotes
Learn when to clone versus initialize a repository, what a remote represents, and how a local project becomes linked to a GitHub-hosted source of truth for collaboration.
1 video7 min
5
Syncing Work: Push and Pull
Understand the local–remote relationship during collaboration: tracking branches, fetch versus pull, push behavior, and what divergence means when histories move independently.
1 video7 min
6
Branching Strategies and Pull Requests
Compare common branching strategies (GitHub Flow, trunk-based, GitFlow-style) and learn how pull requests, code review rules, and merge methods translate branches into safe changes on the main line.
