How to use GitHub as a beginner

GitHub is where code lives. Not just storage — a full history of every version your project has ever been, shared with any person or AI agent you invite. If you're vibe coding, GitHub matters even more than it did for traditional programmers, for one blunt reason: agents move fast and occasionally wreck things, and GitHub is the undo button that makes that survivable.
The save-system mental model
Think of a video game with save points. A repository (repo) is one project's save file. A commit is a save point — a snapshot of every file at one moment, with a note about what changed. A push uploads your local save points to GitHub so they're backed up off your machine. That's the core loop, and it covers most of what you'll ever do: work, commit, push, repeat. Any save point can be restored, which means a bad agent session is never fatal — you roll back to the last commit and try a different prompt.
The two habits that matter for vibe coders
- Commit before big agent tasks. Before letting an agent refactor half your project, say “commit what we have first.” It costs three seconds and buys you a guaranteed way back. This is the single highest-value GitHub habit.
- Read the pull request, not the code. A pull request (PR) is a proposed batch of changes with a summary of what and why. Cloud agents deliver their work as PRs, so your job becomes reading the summary and deciding — the exact review skill vibe coding runs on.
FAQ
What's the difference between Git and GitHub?
Git is the save-point system itself — software running on your machine. GitHub is the website where those save points get backed up and shared. Git works without GitHub; GitHub is what makes it collaborative and cloud-backed.
Do I need to memorize Git commands?
No — your agent runs them when you say “commit this” or “push to GitHub.” What you can't delegate is the concepts: knowing what a commit is tells you when to ask for one, and that timing is the actual skill.
Should my repo be public or private?
Private by default — it's free and it means a leaked mistake (like a secret key) has a limited audience. Go public deliberately, when you want to share the project, and sweep it for secrets first.
