+# Docker Deployment Guide
+
+This guide explains how to run WhatsHooked using Docker and Docker Compose.
+
+## Prerequisites
+
+- Docker installed (version 20.10 or later)
+- Docker Compose installed (version 1.29 or later)
+
+## Quick Start
+
+1. **Copy the example configuration file:**
+   ```bash
+   cp config.example.json config.json
+   ```
+
+2. **Edit the configuration file:**
+   Open `config.json` and update:
+   - WhatsApp phone numbers
+   - Webhook URLs and authentication
+   - Server settings (port, authentication)
+
+3. **Create required directories:**
+   ```bash
+   mkdir -p sessions data/media
+   ```
+
+4. **Build and start the server:**
+   ```bash
+   docker-compose up -d
+   ```
+
+5. **View logs to scan QR code (first run):**
+   ```bash
+   docker-compose logs -f whatshooked
+   ```
+   Scan the QR code with WhatsApp on your phone to authenticate.
+
+6. **Check server health:**
+   ```bash
+   curl http://localhost:8080/health
+   ```
+
+## Docker Commands
+
+### Build the image
+```bash
+docker-compose build
+```
+
+### Start the service
+```bash
+docker-compose up -d
+```
+
+### Stop the service
+```bash
+docker-compose down
+```
+
+### View logs
+```bash
+docker-compose logs -f
+```
+
+### Restart the service
+```bash
+docker-compose restart
+```
+
+### Access the container shell
+```bash
+docker-compose exec whatshooked sh
+```
+
+## Volume Mounts
+
+The docker-compose.yml file mounts three important volumes:
+
+1. **config.json** - Server configuration (read-only)
+2. **sessions/** - WhatsApp session data (persistent authentication)
+3. **data/media/** - Downloaded media files
+
+These volumes ensure your data persists across container restarts.
+
+## Configuration
+
+### Port Mapping
+
+By default, the server runs on port 8080. To change the port:
+
+**Option 1: Update config.json**
+```json
+{
+  "server": {
+    "port": 9090
+  }
+}
+```
+Then update docker-compose.yml:
+```yaml
+ports:
+  - "9090:9090"
+```
+
+**Option 2: Map to different host port**
+```yaml
+ports:
+  - "3000:8080"  # Access via localhost:3000, server still runs on 8080 internally
+```
+
+### Authentication
+
+Set authentication in config.json:
+
+**Option 1: API Key**
+```json
+{
+  "server": {
+    "auth_key": "your-secure-api-key-here"
+  }
+}
+```
+
+**Option 2: Username/Password**
+```json
+{
+  "server": {
+    "username": "admin",
+    "password": "secure-password"
+  }
+}
+```
+
+### Resource Limits
+
+Uncomment the deploy section in docker-compose.yml to set resource limits:
+
+```yaml
+deploy:
+  resources:
+    limits:
+      cpus: '1.0'
+      memory: 512M
+    reservations:
+      cpus: '0.25'
+      memory: 128M
+```
+
+## QR Code Scanning
+
+When you first start the server, you'll need to scan a QR code to authenticate with WhatsApp.
+
+### View QR Code in Logs
+```bash
+docker-compose logs -f whatshooked
+```
+
+The QR code will be displayed in ASCII art in the terminal. Scan it with WhatsApp on your phone:
+1. Open WhatsApp
+2. Go to Settings > Linked Devices
+3. Tap "Link a Device"
+4. Scan the QR code from the terminal
+
+### Alternative: Use CLI Tool
+
+You can also use the CLI tool outside Docker to link accounts, then mount the session:
+```bash
+./bin/whatshook-cli accounts add
+```
+
+## Troubleshooting
+
+### Container won't start
+Check logs for errors:
+```bash
+docker-compose logs
+```
+
+### Config file not found
+Ensure config.json exists in the project root:
+```bash
+ls -la config.json
+```
+
+### Permission issues with volumes
+Fix ownership of mounted directories:
+```bash
+sudo chown -R $(id -u):$(id -g) sessions data
+```
+
+### QR code not displaying
+Ensure `show_qr: true` is set in config.json:
+```json
+{
+  "whatsapp": [
+    {
+      "show_qr": true
+    }
+  ]
+}
+```
+
+### Cannot connect to server
+Check if the container is running:
+```bash
+docker-compose ps
+```
+
+Check health status:
+```bash
+docker inspect whatshooked-server | grep -A 10 Health
+```
+
+## Production Deployment
+
+### Security Best Practices
+
+1. **Use secrets for sensitive data:**
+   - Don't commit config.json with real credentials
+   - Use Docker secrets or environment variables
+   - Enable authentication (auth_key or username/password)
+
+2. **Use HTTPS:**
+   - Put the server behind a reverse proxy (nginx, Traefik, Caddy)
+   - Enable SSL/TLS certificates
+   - Update webhook base_url to use https://
+
+3. **Network isolation:**
+   - Use Docker networks to isolate the service
+   - Only expose necessary ports
+   - Consider using a VPN for webhook endpoints
+
+4. **Regular backups:**
+   - Backup the sessions/ directory regularly
+   - Backup config.json (securely)
+   - Backup media files if needed
+
+### Example with Reverse Proxy (nginx)
+
+Create a network:
+```bash
+docker network create whatshooked-net
+```
+
+Update docker-compose.yml:
+```yaml
+services:
+  whatshooked:
+    networks:
+      - whatshooked-net
+    # Don't expose ports to host, only to network
+    # ports:
+    #   - "8080:8080"
+
+networks:
+  whatshooked-net:
+    external: true
+```
+
+Configure nginx to proxy to the container:
+```nginx
+server {
+    listen 443 ssl;
+    server_name whatshooked.yourdomain.com;
+
+    ssl_certificate /path/to/cert.pem;
+    ssl_certificate_key /path/to/key.pem;
+
+    location / {
+        proxy_pass http://whatshooked:8080;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
+
+## Monitoring
+
+### Health Checks
+
+The compose file includes a health check that runs every 30 seconds:
+```bash
+docker inspect --format='{{.State.Health.Status}}' whatshooked-server
+```
+
+### Log Management
+
+Limit log size to prevent disk space issues:
+```yaml
+services:
+  whatshooked:
+    logging:
+      driver: "json-file"
+      options:
+        max-size: "10m"
+        max-file: "3"
+```
+
+## Updates
+
+To update to the latest version:
+
+1. Pull latest code:
+   ```bash
+   git pull
+   ```
+
+2. Rebuild the image:
+   ```bash
+   docker-compose build --no-cache
+   ```
+
+3. Restart the service:
+   ```bash
+   docker-compose down
+   docker-compose up -d
+   ```
+
+## Multi-Platform Builds
+
+To build for different architectures (e.g., ARM for Raspberry Pi):
+
+```bash
+docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 -t whatshooked:latest .
+```
