-This is an example showing how to use StarkNet React with Next.js
+## Controller Example (Next.js)
 
-## Getting Started
+### Development
 
-First, run the development server:
-
-```bash
-pnpm example:next dev
 ```
+pnpm i
+pnpm dev
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the
-result.
-
-You can start editing the page by modifying `pages/index.tsx`. The page
-auto-updates as you edit the file.
-
-[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on
-[http://localhost:3000/api/hello](http://localhost:3000/api/hello). This
-endpoint can be edited in `pages/api/hello.ts`.
-
-The `pages/api` directory is mapped to `/api/*`. Files in this directory are
-treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead
-of React pages.
