+# Docker Deployment
+
+This application can be easily deployed using Docker with configurable environment variables.
+
+## Quick Start
+
+### Using Docker Run
+
+```bash
+# Run using pre-built image (app will prompt for Navidrome config)
+docker run -p 3000:3000 ghcr.io/sillyangel/mice:latest
+
+# Or build locally
+docker build -t mice .
+docker run -p 3000:3000 mice
+
+# Run with pre-configured Navidrome settings
+docker run -p 3000:3000 \
+  -e NEXT_PUBLIC_NAVIDROME_URL=http://your-navidrome-server:4533 \
+  -e NEXT_PUBLIC_NAVIDROME_USERNAME=your_username \
+  -e NEXT_PUBLIC_NAVIDROME_PASSWORD=your_password \
+  -e PORT=3000 \
+  ghcr.io/sillyangel/mice:latest
+```
+
+### Using Docker Compose
+
+1. Copy the environment template:
+
+   ```bash
+   cp .env.docker .env
+   ```
+
+2. Edit `.env` with your configuration:
+
+   ```bash
+   nano .env
+   ```
+
+3. Start the application:
+
+   ```bash
+   docker-compose up -d
+   ```
+
+**Note**: The default docker-compose.yml uses the pre-built image `ghcr.io/sillyangel/mice:latest`.
+
+For local development, you can use the override example:
+
+```bash
+cp docker-compose.override.yml.example docker-compose.override.yml
+# This will build locally instead of using the pre-built image
+```
+
+## Configuration Options
+
+All configuration is done through environment variables. If Navidrome server configuration is not provided via environment variables, the application will automatically prompt you to configure it within the client interface.
+
+### Optional Variables
+
+- `NEXT_PUBLIC_NAVIDROME_URL`: URL of your Navidrome server (optional - app will prompt if not set)
+- `NEXT_PUBLIC_NAVIDROME_USERNAME`: Navidrome username (optional - app will prompt if not set)
+- `NEXT_PUBLIC_NAVIDROME_PASSWORD`: Navidrome password (optional - app will prompt if not set)
+- `PORT`: Port for the application to listen on (default: `3000`)
+- `HOST_PORT`: Host port to map to container port (docker-compose only, default: `3000`)
+- `NEXT_PUBLIC_POSTHOG_KEY`: PostHog analytics key (optional)
+- `NEXT_PUBLIC_POSTHOG_HOST`: PostHog analytics host (optional)
+
+## Examples
+
+### Basic Setup (App will prompt for configuration)
+
+```bash
+# Using pre-built image - app will ask for Navidrome server details on first launch
+docker run -p 3000:3000 ghcr.io/sillyangel/mice:latest
+
+# Or build locally
+docker build -t mice .
+docker run -p 3000:3000 mice
+```
+
+### Pre-configured Development Setup
+
+```bash
+docker run -p 3000:3000 \
+  -e NEXT_PUBLIC_NAVIDROME_URL=http://localhost:4533 \
+  -e NEXT_PUBLIC_NAVIDROME_USERNAME=admin \
+  -e NEXT_PUBLIC_NAVIDROME_PASSWORD=admin \
+  ghcr.io/sillyangel/mice:latest
+```
+
+### Pre-configured Production Setup
+
+```bash
+docker run -p 80:3000 \
+  -e NEXT_PUBLIC_NAVIDROME_URL=https://music.yourdomain.com \
+  -e NEXT_PUBLIC_NAVIDROME_USERNAME=your_user \
+  -e NEXT_PUBLIC_NAVIDROME_PASSWORD=your_secure_password \
+  -e PORT=3000 \
+  --restart unless-stopped \
+  ghcr.io/sillyangel/mice:latest
+```
+
+### Using Environment File
+
+#### Option 1: Let the app prompt for configuration
+
+Create a minimal `.env` file:
+
+```env
+PORT=3000
+HOST_PORT=80
+```
+
+#### Option 2: Pre-configure Navidrome settings
+
+Create a `.env` file with Navidrome configuration:
+
+```env
+NAVIDROME_URL=https://music.yourdomain.com
+NAVIDROME_USERNAME=your_user
+NAVIDROME_PASSWORD=your_secure_password
+PORT=3000
+HOST_PORT=80
+```
+
+Then run either way:
+
+```bash
+docker-compose up -d
+```
+
+## Health Check
+
+The Docker Compose setup includes a health check that verifies the application is responding correctly. You can check the health status with:
+
+```bash
+docker-compose ps
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Connection refused**: Ensure your Navidrome server is accessible from the Docker container
+2. **Authentication failed**: Verify your username and password are correct
+3. **Port conflicts**: Change the `HOST_PORT` if port 3000 is already in use
+
+### Logs
+
+View application logs:
+
+```bash
+# Docker run
+docker logs <container_name>
+
+# Docker compose
+docker-compose logs -f mice
+```
+
+### Container Shell Access
+
+Access the container for debugging:
+
+```bash
+# Docker run
+docker exec -it <container_name> sh
+
+# Docker compose
+docker-compose exec mice sh
+```
