Start reading →- 01 What Claude Code actually is An AI that opens on your desktop, sees the folder you point it at, and does real work on your actual files — not a chat window you paste things into. 3 min
- 02 Get it on your computer Download the Claude desktop app, run the installer, sign in with your Claude account. The same download-and-double-click you've done a hundred times. 5 min
- 03 Your first conversation Open a folder in the app, ask a question about it in the chat, and watch Claude go and look at your real files before it answers. 4 min
- 04 What Claude can see Claude is scoped to the folder you opened. Not your other windows, not your browser, not your screen. The open folder is the world. 3 min
- 05 When Claude asks permission Before Claude changes a file or runs anything, it stops and asks. That pause is the most important feature in the app, and the one people are most tempted to switch off. 4 min
- 06 Your first real change Ask for one specific change, read the before-and-after Claude shows you, then click Accept or Reject. The file doesn't move until you click. 5 min
- 07 How to undo anything Reject costs nothing, Undo costs a click, and a version-control restore is the deep net. Know your way back before you accept, not after. 4 min
- 08 Where it goes wrong Claude is sometimes confidently wrong. The fix isn't a setting — it's a two-second habit you do every time it tells you something that matters. 4 min
That's the whole path.
Everything after this is depth on a foundation you now have. Each subject has its own page — the definitions, what it looks like in the app, the comparisons, and the long reads, all in one place.
