```

## Setup

1. Install dependencies:
```bash
pip install -r requirements.txt
```

2. Run the application:
```bash
python app.py
```

3. Visit http://127.0.0.1:3000 in your browser

## Environment Variables

The app can be configured via environment variables:

- `SECRET_KEY` - Flask secret key (defaults to 'your-secret-key')
- `PORT` - Port to run on (defaults to 3000)
- `DEBUG` - Enable debug mode (defaults to False)

**Development:**
```bash
export DEBUG=True
python app.py
```

**Production:**
```bash
export SECRET_KEY="your-secure-random-secret-key"
export PORT=3000
python app.py
```

## Adding Comics

Comics are stored in the `COMICS` list in `comics_data.py`. Each comic entry:

```python
{
    'number': 1,                           # Comic number (required, sequential)
    'filename': 'comic-001.png',           # Image filename (required)
    'date': '2025-01-01',                  # Publication date (required)
    'alt_text': 'Alt text for comic',      # Accessibility text (required)
    'title': 'Comic Title',                # Title (optional, shows #X if absent)
    'author_note': 'Optional note'         # Author note (optional)
}
```

### Adding a New Comic

**Option 1: Use the script (recommended)**
```bash
# Add comic entry only
python scripts/add_comic.py

# Add comic entry AND create markdown file for author notes
python scripts/add_comic.py -m
```
This will automatically add a new entry with defaults. The `-m` flag creates a markdown file in `content/author_notes/{date}.md` with a template. Then edit `comics_data.py` to customize.

**Option 2: Manual**
1. Save your comic image in `static/images/comics/` (e.g., `comic-001.png`)
2. Optionally, create a thumbnail in `static/images/thumbs/` with the same filename
3. Add the comic entry to the `COMICS` list in `comics_data.py`

### Generating RSS Feed

After adding comics, regenerate the RSS feed:
```bash
python scripts/generate_rss.py
```
This creates/updates `static/feed.rss`

## Production Deployment

For production, you should **NOT** use Flask's built-in development server. Choose one of the following deployment methods:

### Option 1: Docker (Recommended)

**1. Generate a secure secret key:**
```bash
python -c "import secrets; print(secrets.token_hex(32))"
```

**2. Create a `.env` file:**
```bash
SECRET_KEY=your-generated-secret-key-here
```

**3. Build and run with Docker Compose:**
```bash
docker-compose up -d
```

**Or build and run manually:**
```bash
# Build the image
docker build -t sunday-comics .

# Run the container
docker run -d \
  -p 3000:3000 \
  -e SECRET_KEY="your-secret-key" \
  -v $(pwd)/comics_data.py:/app/comics_data.py:ro \
  -v $(pwd)/static/images:/app/static/images:ro \
  --name sunday-comics \
  sunday-comics
```

**View logs:**
```bash
docker-compose logs -f
```

### Option 2: Manual Deployment with Gunicorn

**1. Generate a Secure Secret Key**

```bash
python -c "import secrets; print(secrets.token_hex(32))"
```

**2. Set Environment Variables**

```bash
export SECRET_KEY="generated-secret-key-from-above"
export DEBUG=False
export PORT=3000
```

**3. Use a Production WSGI Server**

**Install Gunicorn:**
```bash
pip install gunicorn
```

**Run with Gunicorn:**
```bash
gunicorn app:app --bind 0.0.0.0:3000 --workers 4
```

### Using a Reverse Proxy (Recommended)

Set up Nginx or another reverse proxy in front of your app for:
- HTTPS/SSL termination
- Static file serving
- Load balancing
- Better security

### Additional Production Considerations

- Use a process manager (systemd, supervisor) for non-Docker deployments
- Set appropriate file permissions
- Enable HTTPS with Let's Encrypt
- Consider using a CDN for static assets
- Monitor logs and performance
- Set up automated backups of `comics_data.py`

## Upgrading to a Database

For larger comic archives, consider replacing the `COMICS` list with a database:

- SQLite for simple setups
- PostgreSQL/MySQL for production
- Use Flask-SQLAlchemy for ORM support

## Customization

### Branding
- Update "Sunday Comics" references in `templates/base.html`
- Update site title and footer text

### Styling
- Modify `static/css/style.css` to change colors, fonts, and layout
- Current color scheme uses blue (#3498db) and dark blue-gray (#2c3e50)

### About Page
- Edit `templates/about.html` to add your bio and comic information

## Pages

- `/` - Shows the latest comic
- `/comic/<id>` - View a specific comic by number
- `/archive` - Browse all comics in a grid
- `/about` - About the comic and author
- `/static/feed.rss` - RSS feed

## API Endpoints

The app exposes a JSON API for programmatic access:

- **GET `/api/comics`** - Returns all comics as a JSON array
  ```json
  [
    {
      "number": 1,
      "title": "First Comic",
      "filename": "comic-001.png",
      "date": "2025-01-01",
      "alt_text": "The very first comic",
      "author_note": "This is where your comic journey begins!"
    }
  ]
  ```

- **GET `/api/comics/<id>`** - Returns a specific comic as JSON
  ```json
  {
    "number": 1,
    "title": "First Comic",
    "filename": "comic-001.png",
    "date": "2025-01-01",
    "alt_text": "The very first comic",
    "author_note": "This is where your comic journey begins!"
  }
  ```

  Returns 404 with `{"error": "Comic not found"}` if the comic doesn't exist.
