🫰 Best Snap Hacks — 2x $1,000 each

  • Monorepo - Use a monorepo structure (scaffold projects with the guide or the CLI to get started). Feel free to construct a more complex front-end React.
  • README - README should detail what the project is, what it aims to accomplish, steps for running locally etc.
