   ```

2. **Access the application**
   - Open http://localhost:3000 in your browser

#### Option 2: Build from Source

1. **Clone the repository**
   ```bash
   git clone https://github.com/Ryderjj89/esv-bible.git
   cd esv-bible
   ```

2. **Build and run with Docker (with persistent storage)**
   ```bash
   docker build -t esv-bible .
   docker run -p 3000:3000 -v esv-bible-data:/app/backend/data esv-bible
   ```

3. **Access the application**
   - Open http://localhost:3000 in your browser

### Docker Compose Setup (Recommended)

1. **Run with docker-compose**
   ```bash
   docker-compose up -d
   ```
   
   This will:
   - Build the application automatically
   - Create a persistent volume for database storage
   - Start the service in the background
   - Make the app available at http://localhost:3000

2. **View logs (optional)**
   ```bash
   docker-compose logs -f
   ```

3. **Stop the application**
   ```bash
   docker-compose down
   ```

4. **Update to latest version**
   ```bash
   docker-compose pull
   docker-compose up -d
   ```

## Authentication Setup (Optional)

To enable user authentication and features like favorites and synced preferences, configure OpenID Connect:

### Environment Variables

Create a `.env` file in the root directory with the following variables:

#### Example Configuration (Authentik)
