+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app) configured for **Server-Side Rendering (SSR)**.
+
+This example demonstrates how to use Firebase UI with Next.js App Router using server-side rendering. Unlike the static export version (`nextjs`), this version uses Next.js SSR capabilities including:
+
+- Server Components for initial page rendering
+- Server-side authentication state checking using `getCurrentUser()` from `serverApp.ts`
+- Server-side redirects using `redirect()` from `next/navigation`
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Differences from Static Export Version
+
+- **No `output: "export"`** in `next.config.ts` - enables SSR
+- **Server Components** - Pages use `async` functions and `getCurrentUser()` from `serverApp.ts`
+- **Server-side redirects** - Uses `redirect()` instead of client-side `useRouter().push()`
+- **Server-side auth checks** - Authentication state is checked on the server before rendering
+
+## 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.
+- [Next.js Server Components](https://nextjs.org/docs/app/building-your-application/rendering/server-components) - learn about server-side rendering
+- [Learn Next.js](https://nextjs.org/learn) - 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
+
+This app can be deployed to Firebase Hosting or any Node.js hosting platform that supports Next.js SSR:
+
+```bash
+pnpm run deploy
+```
+
+For Firebase Hosting, ensure you have configured the hosting site `fir-ui-2025-nextjs-ssr` in your Firebase project.
