1. What it is, in one image
Think of it as Google Drive for your project, but with total memory. Every time something changes, GitHub keeps a dated snapshot of the previous state. Nothing is ever lost, and you can roll back to any version with one click if a change breaks everything.
That's the game-changer: you work without fear. You test, you break things, you roll back. A mistake stops being a disaster.
- Initial version
- Homepage redesign↩ roll back here
- Added pricing section
- Change that broke everything 😬
2. Why it's free (and not a gimmick)
GitHub is owned by Microsoft and its free tier comfortably covers the needs of a freelancer or small business. It's not a stripped-down "try it" version — entire companies run on it. The paid plans are only needed for advanced team use.
Another advantage: it's become the standard. When you hand off work to a developer or agency, "it's on GitHub" is all you need to say — everyone speaks the same language.
3. "Once connected, it updates itself"
This is the click. You connect once — your site, or your shop theme, for example. After that, every change pushed to GitHub deploys automatically online. No FTP, no "let me re-upload the right file."
In my setup, it's become wild: my site, my Shopify theme, and even automations tied to Odoo all live on GitHub. Claude Code pushes the changes, and they're live a minute later. I almost never open the hood.
4. You don't need to understand all of it
Good news for non-technical people: you don't need to master GitHub. Claude Code handles version control for you (backups, history, deployment); you just approve. GitHub runs in the background like a safety net.
