What you need

This guide takes a PRD and turns it into a working app prototype over a weekend. You do not write the code. You set up the folder, give Claude Code the plan, and let it build version one.

Collect three things before you start:

  • A PRD for the app, saved as a markdown file.
  • An IDE, such as Google Antigravity, which the source names as a good free option.
  • Claude Code, running inside that IDE.

The goal is a prototype you can open in a browser. It will not be finished. That is the point of version one.
