## 🚀 Quick Start

For a detailed 5-minute setup guide, see [QUICKSTART.md](QUICKSTART.md).

```bash
# 1. Configure environment
cp backend/.env.example backend/.env
# Edit backend/.env with your email settings

# 2. Start everything (Auto-detects GPU)
./start-with-gpu.sh

# Questions?
# See logs: docker-compose logs -f
```

The system will automatically:
1.  **6:00 AM**: Crawl news & transport updates.
2.  **6:30 AM**: Generate AI summaries & clusters.
3.  **7:00 AM**: Send personalized newsletters.

## 📋 System Architecture

The system is built as a set of microservices orchestrated by Docker Compose.

## 🛠️ Installation & Setup

1.  **Clone the repository**
    ```bash
    git clone https://github.com/yourusername/munich-news.git
    cd munich-news
    ```

2.  **Environment Configuration**
    ```bash
    cp backend/.env.example backend/.env
    nano backend/.env
    ```
    *Critical settings:* `SMTP_SERVER`, `EMAIL_USER`, `EMAIL_PASSWORD`.

3.  **Start the System**
    ```bash
    # Recommended: Helper script (handles GPU & Model setup)
    ./start-with-gpu.sh
    
    # Alternative: Standard Docker Compose
    docker-compose up -d
    ```

4.  **Initial Setup (First Run)**
    *   The system needs to download the AI model (approx. 2GB).
    *   Watch progress: `docker-compose logs -f ollama-setup`

## ⚙️ Configuration

Key configuration options in `backend/.env`:

| Category | Variable | Description |
|----------|----------|-------------|
| **Email** | `SMTP_SERVER` | SMTP Server (e.g., smtp.gmail.com) |
| | `EMAIL_USER` | Your sending email address |
| **AI** | `OLLAMA_MODEL` | Model to use (default: phi3:latest) |
| **Schedule** | `CRAWLER_TIME` | Time to start crawling (e.g., "06:00") |
| | `SENDER_TIME` | Time to send emails (e.g., "07:00") |

## 📊 Usage & Monitoring

### Access Points
*   **Web Dashboard**: [http://localhost:3000](http://localhost:3000) (or configured domain)
*   **API**: [http://localhost:5001](http://localhost:5001)

### Useful Commands

**View Logs**
```bash
docker-compose logs -f [service_name]
# e.g., docker-compose logs -f crawler
```

**Manual Trigger**
```bash
# Run News Crawler immediately
docker-compose exec crawler python crawler_service.py 10

# Run Transport Crawler immediately
docker-compose exec transport-crawler python transport_service.py

# Send Test Newsletter
docker-compose exec sender python sender_service.py test user@example.com
```

**Database Access**
```bash

```

## 🌐 Production Deployment (Traefik)

This project is configured to work with **Traefik** as a reverse proxy.
The `docker-compose.yml` includes labels for:
- `news.dongho.kim` (Frontend)
- `news-api.dongho.kim` (Backend)

To use this locally, add these to your `/etc/hosts`:
```text
127.0.0.1 news.dongho.kim news-api.dongho.kim
```

For production, ensure your Traefik proxy network is named `proxy` or update the `docker-compose.yml` accordingly.
