 This guide explains how to use Docker to build and run the Svelte MUD client.

+This setup runs both the SvelteKit application and the WebSocket server in a single container, avoiding CORS issues. It follows the same approach used in development, where both servers run as separate processes but within the same context.

-## Configuration
+## Caddy Configuration
 
-The Docker setup uses a single port for both the web interface and WebSocket server:
+For use with Caddy as a reverse proxy, use this simple configuration:
-- Port 3000: Unified server (Web + WebSocket)
 
-You can modify these ports in the `docker-compose.yml` file if needed.
+```
-
+mud.example.com {
-## Customization
+    reverse_proxy svelte-mud:3000
-
+}
-### Environment Variables
-
-You can add environment variables in the `docker-compose.yml` file:
-
-```yaml
-services:
-  svelte-mud:
-    environment:
-      - NODE_ENV=production
-      - PORT=3000
-      # Add your custom environment variables here
 ```
 
-### Building for Production
+Both the web interface and WebSocket connections will be routed correctly through this single reverse proxy rule.
-
-The default configuration is optimized for production use. It:
-- Uses a multi-stage build process to minimize image size
-- Runs as a non-root user for better security
-- Includes only production dependencies
 
 ## Troubleshooting
 
-1. **Port conflicts**: If port 3000 is already in use, modify the port mapping in `docker-compose.yml`.
+If you encounter any issues, check the container logs:
 
-2. **Build failures**: Ensure that all dependencies are properly defined in your package.json.
+```bash
-
+docker-compose logs -f
-3. **Connection issues**: If you can't connect to the WebSocket server, verify that your client is using the correct URL format: `ws://localhost:3000/mud-ws?host=YOUR_MUD_HOST&port=YOUR_MUD_PORT`.
