Learn Claude Code
starting from literally
zero technical knowledge.
Most tutorials start in the middle. This one starts at the start — what a computer is, what a file is, what code is — and ends with multi-agent workflows on real projects. No shortcuts. No assumptions about what you already know.
The complete beginner
You've never opened a terminal, never seen code, never thought of yourself as 'technical.' Module 1 starts with what a file actually is.
The dabbling tinkerer
You've copied a Python script off the internet. You can edit HTML. Jump into Module 2 or 3 and skip what's already obvious.
The existing Claude user
You ship code with Claude every week. Module 4 is for you — subagents, hooks, MCP, scheduled work, and the mindset shift after.
From what is a computer to running agents in parallel.
Absolute Zero
No assumptions. We start at the start.
If you've never written a line of code, never opened a terminal, and aren't sure what 'a file' really is — this is where you begin. By the end you'll know what a computer is doing when you press a key.
Software Basics
The shared vocabulary every developer takes for granted.
Before Claude Code can be useful to you, you need to know what it's looking at. This module is the working knowledge a junior developer picks up in their first month — compressed into bite-sized lessons.
Claude Code Fundamentals
From install to your first real session.
The core mechanics of Claude Code: how to install it, how to talk to it, how it sees your project, and the small habits that separate people who get value from it from people who don't.
Advanced Usage
Become the engineering manager of your own AI team.
You're past the basics. Now we wire Claude into your real workflow — multiple agents in parallel, custom tools, hooks, scheduled work, and the judgment to know when each is the right call.
A real working knowledge — not a survey of buzzwords.
Plain language
Every term is defined the first time it appears. You will never have to leave the page to look up jargon.
No code prerequisites
You will be able to read code by the end. You don't need to come in knowing any.
Reasoning, not recipes
The why behind every tool, so you can adapt when your situation is slightly different from the example.
Built to be re-read
A curriculum, not a one-time tour. Come back to lesson 12 a month later and it still pays.
