-# Web
+## Getting Started
 
-This
-
-## Development
-
-First, install Turborepo globally. Even though `turbo` is installed globally, when any global `turbo` commands are run from the terminal, it [uses the local version](https://turborepo.com/docs/crafting-your-repository/running-tasks#using-global-turbo) specified in `package.json` located at repo's root.
+First, run the development server:
 
 ```bash
-pnpm install turbo --global
+pnpm dev
 ```
 
-Run the development server using Turborepo. The reason we use Turborepo to run the development command as opposed to `pnpm dev` is because the app might depend on other monorepo packages in and they have to be built before the Next.js app can run:
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
 
-```bash
-turbo dev
-```
+You can start editing the page by modifying `pages/index.js`. 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.js`.
+
+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.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn/foundations/about-nextjs) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_source=github.com&utm_medium=referral&utm_campaign=turborepo-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
