All twenty-eight lessons are free, with no sign-up. Part two uses Claude Code, which needs a paid Claude plan - the course itself costs nothing. **### Do I need to be a programmer?** Not for part one, which covers Claude the app and needs no terminal. Part two is Claude Code on a real codebase and assumes you can run a command and read a diff. **### How long does the course take?** About five hours of reading across twenty-eight lessons, and every lesson ends with something you do on your own machine rather than something you watch. **### What codebase does part two use?** A small inventory tool called stockroom, cloned from GitHub in lesson 11, with real bugs planted in it so the exercises look like the work you actually get paid for.
