Thank you for the feedback!
We’ve updated Lesson 0 to specify the required Node.js/npm versions and made it clear that all commands must be run from the project folder containing package.json.
When you run commands from the repo’s root directory (the folder containing package.json), Vite is installed automatically as a dev dependency - so you don’t need to install it manually.
If you still see a 404 at http://localhost:5173/, it usually means the dev‑server was started from the wrong directory (one without index.html and package.json). Please make sure you’re in the repo folder and let us know if you hit any other snags!
