wesammustafa/Claude-Code-Everything-You-Need-to-Know

Learn Claude Code in three levels, from your first session to unattended multi-agent runs.

You learn by doing: every core lesson and capstone ends with a check you run in your own practice copy, and every Beginner lesson and the capstone run step by step in a terminal app beside Claude Code.

_{The learning app, npm run learn, on its first run.}

You need a paid Claude plan (Pro, Max, Team or Enterprise), a Claude Console account, or a supported cloud provider (Quickstart), plus Node.js LTS and git.

1. Make your practice copy: open claude-code-practice, select Use this template > Create a new repository, and clone your copy. Or open your copy in a Codespace, where Node.js and Claude Code come preinstalled.

2. In your copy, start the app:

   npm run learn

3. Open a second terminal in the same folder. The app tells you what to type there, starting with installing Claude Code, and checks your work as you go.

The app teaches every Beginner lesson and the capstone. It has no AI in it and changes none of your work.

For Intermediate and Advanced, or if you prefer to read, every lesson works from its page alone. Each core lesson ends with a check you run from your practice copy, for example npm run check -- b-1: each item prints PASS or FAIL, with a hint for what to fix.

The help shrinks each time a skill comes back: GUIDED shows every command, HINTED gives the goal and a hint each time you press h, and CHALLENGE gives just the goal.

Step 1 of 12, GUIDED: the exact command, and the window to type it in.	Step 11 of 12, CHALLENGE: the goal alone, while the app watches your copy.
