-> Node.js 20 or newer is recommended.
+Next.js 14 · Tailwind CSS · daisyUI · react-chessboard · chess.js · Express.js · Socket.io · PostgreSQL · TypeScript · Docker
 
-This project is structured as a monorepo using **pnpm** workspaces, separated into three packages:
+## Deployment (NAS / Docker)
 
-- `client` - Next.js application for the front-end, ~~deployed to ches.su via Vercel~~.
-- `server` - Node/Express.js application for the back-end, ~~deployed to server.ches.su via Railway~~.
-- `types` - Shared type definitions required by the client and server.
+```bash
+# 1. Repository klonen
+git clone https://git.mischlabs.de/MrDiderot/MiChess.git michess
+cd michess
 
-### Getting started
+# 2. Konfiguration anpassen
+cp .env.example .env
+nano .env   # Passwörter, ADMIN_EMAIL etc. setzen
 
-1. Install [pnpm](https://pnpm.io/installation).
-2. Install the necessary dependencies by running `pnpm install` in the root directory of the project.
-3. In the `server` directory, create a `.env` file for your PostgreSQL database. You can try [ElephantSQL](https://www.elephantsql.com/) or [Aiven](https://aiven.io/postgresql) for a free hosted database.
-   ```env
-   PGHOST=db.example.com
-   PGUSER=exampleuser
-   PGPASSWORD=examplepassword
-   PGDATABASE=chessu
-   ```
-4. Run the development servers with `pnpm dev`.
-   - To run the frontend and backend servers separately, use `pnpm dev:client` and `pnpm dev:server`, respectively.
-5. You can now access the frontend at http://localhost:3000 and the backend at http://localhost:3001.
-
-## Running chessu with Docker
-
-To build the project with Docker, you can use the provided `Dockerfile`.
-```sh
-docker build -t chessu .
+# 3. Starten
+docker compose up -d --build
 ```
 
-This command will build the Docker image with the name `chessu`. You can then run the image with the following command:
-```sh
-docker run -p 3000:3000 -p 3001:3001 chessu
+Frontend: `http://deine-nas-ip:3000`
+Backend API: `http://deine-nas-ip:3001`
+
+## Update
+
+```bash
+# Manuell via Script
+./scripts/update.sh
+
+# Oder im Admin-Panel → "Jetzt aktualisieren"
 ```
 
-Once built, to start the project with POSTGRES, you can use the provided `docker-compose.yml` file.
-```sh
-docker-compose up
+## Entwicklung (lokal)
+
+```bash
+pnpm install
+pnpm dev
 ```
-Please make sure to modify the values in the `server/.env` file to match the values in the `docker-compose.yml` file or vice versa.
 
-The entrypoint for the Docker image is set to run pnpm.
-The Dockerfile's `CMD` instruction is set to run the project in production mode. 
-If you want to run the project in development mode, you can override the `CMD` instruction by running the following command:
-```sh
-docker run -p 3000:3000 -p 3001:3001 chessu dev # runs both client and server in development mode
-docker run -p 3000:3000 -p 3001:3001 chessu dev:client # runs only the client in development mode
-docker run -p 3000:3000 -p 3001:3001 chessu dev:server # runs only the server in development mode
-```
