+[Next.js](https://nextjs.org/) is a React framework for building full-stack web applications. It supports server-side rendering, static site generation, API routes, and more. Bun provides fast package installation and can run Next.js development and production servers.

-You can specify a starter template using the `--example` flag.
+<Steps>
+  <Step title="Create a new Next.js app">
+    Use the interactive CLI to create a new Next.js app. This will scaffold a new Next.js project and automatically install dependencies.
 
-```sh
-bun create next-app --example with-supabase
-```
+    ```sh terminal icon="terminal"
+    bun create next-app@latest my-bun-app
+    ```
 
-```txt
-✔ What is your project named? … my-app
-...
-```
+  </Step>
+  <Step title="Start the dev server">
+    Change to the project directory and run the dev server with Bun.
+
+    ```sh terminal icon="terminal"
+    cd my-bun-app
+    bun --bun run dev
+    ```
+
+    This starts the Next.js dev server with Bun's runtime.
+
+    Open [`http://localhost:3000`](http://localhost:3000) with your browser to see the result. Any changes you make to `app/page.tsx` will be hot-reloaded in the browser.
+
+  </Step>
+  <Step title="Update scripts in package.json">
+    Modify the scripts field in your `package.json` by prefixing the Next.js CLI commands with `bun --bun`. This ensures that Bun executes the Next.js CLI for common tasks like `dev`, `build`, and `start`.
+
+    ```json package.json icon="file-json"
+    {
+      "scripts": {
+        "dev": "bun --bun next dev", // [!code ++]
+        "build": "bun --bun next build", // [!code ++]
+        "start": "bun --bun next start", // [!code ++]
+      }
+    }
+    ```
+
+  </Step>
+</Steps>

-To start the dev server with Bun, run `bun --bun run dev` from the project root.
+## Hosting
 
-```sh terminal icon="terminal"
-cd my-app
-bun --bun run dev
-```
+Next.js applications on Bun can be deployed to various platforms.
