-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).
+# BinouzUHC
 
-## Getting Started
+Modern Minecraft UHC landing page with Discord authentication, admin panel, and a ready-to-docker stack.
 
-First, run the development server:
+## Stack
+
+- Next.js (App Router) + TypeScript
+- Tailwind CSS
+- Prisma + PostgreSQL
+- NextAuth (Discord OAuth)
+- Docker / docker-compose
+
+## Quick start (Docker)
+
+1. Copy env file:
 
 ```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
+cp .env.example .env
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+2. Fill the values in `.env`:
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+```txt
+NEXTAUTH_SECRET=
+NEXTAUTH_URL=http://localhost:3000
 
-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.

+3. Build and run:
 
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+```bash
+docker compose up --build
+```
 
-## Deploy on Vercel
+4. (Optional) Seed initial grades/events:
 
-The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+```bash
+docker compose exec app npm run db:seed
+```
 
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
+Open http://localhost:3000.
+
+## Admin access
+
+- Set `ADMIN_DISCORD_ID` in `.env` to the Discord user ID that should be admin.
+- First sign-in will automatically register the user and grant admin access.
+- Admin panel: `/admin`.
+
+## Local development (no Docker)
+
+```bash
+npm install
+npm run prisma:migrate
+npm run dev
+```
+
+## Project structure
+
+```
+app/            App Router pages, layouts, API routes
+components/     UI and dashboard components
+lib/            Auth, db, helpers
