+### Synology NAS Setup
+
+This guide covers running Monochrome on a Synology NAS using Docker.
+
+#### Prerequisites
+
+- Docker Package installed on your Synology
+- SSH access to your NAS (optional, for troubleshooting)
+
+#### Step 1: Prepare Directories
+
+1. Create a shared folder for Monochrome (e.g., `docker/monochrome`)
+2. Upload the project files to this folder, or clone directly via SSH:
+    ```bash
+    cd /volume1/docker/monochrome
+    git clone https://github.com/monochrome-music/monochrome.git .
+    ```
+
+#### Step 2: Configure Environment
+
+1. Navigate to the `docker` folder
+2. Copy the `.env` file (or create from `.env.local`):
+    ```bash
+    cd docker
+    cp .env.local .env
+    ```
+3. Edit `.env` with your settings:
+
+    ```bash
+    # Port for the web interface
+    MONOCHROME_PORT=3000
+
+    # Enable authentication (set to true to require login)
+    AUTH_ENABLED=false
+
+    # Secret key - generate with: openssl rand -base64 32
+    AUTH_SECRET=your-random-secret-key-here
+
+    # PocketBase URL (internal Docker network)
+    POCKETBASE_URL=http://pocketbase:8090
+
+    # Session duration (7 days in milliseconds)
+    SESSION_MAX_AGE=604800000
+
+    # PocketBase Admin credentials
+    PB_ADMIN_EMAIL=admin@monochrome.local
+    PB_ADMIN_PASSWORD=your-secure-password
+    TZ=Asia/Ho_Chi_Minh  # Adjust to your timezone
+    POCKETBASE_PORT=8090
+    ```
+
+#### Step 3: Start the Container
+
+Using SSH or the Docker UI:
+
+```bash
+cd /volume1/docker/monochrome/docker
+docker compose up -d
+```
+
+Or in Docker Desktop / Container Manager:
+
+1. Navigate to your project folder
+2. Select `docker-compose.yml`
+3. Click "Run"
+
+#### Step 4: Access the Application
+
+- **Local:** `http://<your-nas-ip>:3000`
+- **External:** Set up Synology Reverse Proxy (see below)
+
+#### Optional: Set Up Reverse Proxy (HTTPS)
+
+1. Go to **Control Panel > Application Portal > Reverse Proxy**
+2. Click **Create**
+3. Configure:
+    - **Source:**
+        - Protocol: HTTPS
+        - Hostname: `monochrome.yourdomain.com` (your domain)
+        - Port: 443
+    - **Destination:**
+        - Protocol: HTTP
+        - Hostname: `localhost`
+        - Port: 3000
+4. Save and access via `https://monochrome.yourdomain.com`
+
+#### Optional: Enable User Authentication
+
+1. Edit `.env`:
+    ```bash
+    AUTH_ENABLED=true
+    ```
+2. Restart the container:
+    ```bash
+    docker compose down && docker compose up -d
+    ```
+
+#### Common Commands
+
+```bash
+# View logs
+docker compose logs -f
+
+# Restart
+docker compose restart
+
+# Update & rebuild
+docker compose pull && docker compose up -d --build
+
+# Stop
+docker compose down
+
+# Stop and remove data (WARNING: loses all user data)
+docker compose down -v
+
+# Backup PocketBase data
+docker compose exec pocketbase tar czf - /pb_data > ../backup_monochrome.tar.gz
+
+# Restore PocketBase data
+docker compose exec pocketbase tar xzf - -C / < ../backup_monochrome.tar.gz
+```
