Key point
One idea
Start with App Router from day one. In Next.js, routes come from files, and the app folder is where your project will grow.
For this track, your repo must clearly show App Router files. Do not start with an older Pages Router tutorial and try to convert it at 2 am.
What you create
You will create a Next.js app using create-next-app. The current default setup gives you TypeScript, Tailwind CSS, ESLint, App Router, Turbopack, the @/* import alias, and AGENTS.md.
You only need the starter today. Later lessons will add routes, Server and Client Components, server data fetching, and a route handler.
