What GitHub Actually Is

Let's start with the fear, because everybody has it: you spend an afternoon building something, you change one thing, and suddenly it's broken — and you can't get back to the version that worked. That sinking feeling? GitHub exists to make it impossible.

GitHub is two things at once: a tool that saves a snapshot of your entire project every time you want, and a safe backup of all those snapshots in the cloud. Put together: you can always go back, and your work can never be lost to a dead laptop.

A useful way to picture it

You know "Track Changes" in a Word document — every edit recorded, nothing truly gone? GitHub is Track Changes for your whole project, plus an automatic off-site backup. Every saved version is there. Made a mess today? Roll back to yesterday's working version in seconds.

Two words you'll hear — demystified

  • Git is the save-point tool that lives on your computer. It takes the snapshots.
  • GitHub is the website where those snapshots get backed up and shared. It's your project's home on the internet.

That's the whole distinction. Git saves; GitHub stores and shares. People say "GitHub" to mean both, and that's fine.

Why this matters for you

Three reasons a business owner cares:

  1. You never lose work. Laptop dies? Your project is safe in the cloud.
  2. You can undo anything. Every version is recoverable — experiment fearlessly.
  3. It's how your project goes live. Hosting services publish your site straight from GitHub. It's the bridge from "on my computer" to "on the internet."

And here's the relief: Claude Code handles all the mechanics for you. You don't memorize commands. You just need to understand the idea — which you now do. The rest of this course shows you how to use it, in plain English, with Claude doing the typing.

▶️ Try this

Just notice the feeling you want to avoid: that "I lost my work / I broke it and can't go back" panic. By the end of this short course, that feeling is gone for good — you'll have a safety net under everything you build.
