 ## Getting Started
 
-### Prerequisites
+### Docker Deployment (Recommended)
 
+The easiest way to run the calendar is using Docker Compose:
+
+1. **Clone the repository**:
+   ```bash
+   git clone <repository-url>
+   cd calendar
+   ```
+
+2. **Start the application**:
+   ```bash
+   docker compose up
+   ```
+
+3. **Access the application** at `http://localhost`
+
+The Docker setup includes:
+- **Automatic database migrations** on startup
+- **Persistent data storage** in `./data/db/` volume
+- **Frontend served via Caddy** on port 80
+- **Backend API** accessible on port 3000
+
+### Development Setup
+
+#### Prerequisites
 - Rust (latest stable version)
 - Trunk (`cargo install trunk`)
 
-### Development Setup
