Claude Code: Zero To Hero

Learn Claude Code end to end — from your first session to building products on the Agent SDK. Written for developers, DevOps, cloud, SRE, and platform engineers who want to actually use it, not just watch a demo.

Sixteen modules, four phases, a two-track capstone. Every fact is verified against Anthropic's official documentation, and every module carries the date it was last checked.

The course

Phase 1 · Zero → Comfortable

Understand what you're using, and get it running.

Phase 2 · Comfortable → Productive

The tools, the guardrails, and how to extend both.

Phase 3 · Productive → Advanced

Many agents, every surface, and the boundaries an organisation sets.

Phase 4 · Advanced → Hero

Build with it, then build something with it.

🔬 = deep-dive module — longer, with hands-on exercises, common pitfalls, and key takeaways per chapter.

Everyone takes Modules 1–14. Module 15 splits into two tracks so a frontend developer and an SRE each leave with a portfolio piece that matches their job. Module 13 is not optional on either track — it's what makes this different from a generic AI coding tutorial.

Reference

Six ways to find something without reading a whole module:

How to use this

• Read in order the first time. Modules build on each other — Module 7 makes much more sense after Module 5.
• Every module ends with links to the previous and next one, so you can read straight through.
• "Try it yourself" blocks assume a practice repo. See labs/ for what it needs to contain — or use any project of your own with a failing test in it.
• Claude Code ships weekly. Each module carries a last_verified date in an HTML comment at the top. Anything version-specific — model IDs, prices, flags, command names — is worth a re-check before you rely on it for something critical. Module 16 covers how.

Contributing

Corrections are welcome, especially version drift — a command that was renamed, a flag that changed, a limit that moved. That's the most valuable kind of PR this repo can get.

Before opening one that touches module content:

1. Verify against official docs. Start at code.claude.com/docs/llms.txt for the index and whats-new for recent changes. Third-party recap posts have been unreliable.
2. Update the last_verified date in the module's HTML comment.
3. Keep the references in sync — a change to a module usually needs the same change in reference/quick-reference.md, and sometimes in reference/commands.md.
4. Don't state what you can't verify. If a fact isn't in the official docs, cut it rather than shipping it.
