+
+## Features
+
+### 🎯 **Automatic PDF Generation**
+- Generates PDF reports automatically after each analysis
+- Uses Playwright as primary engine (cross-platform, no system dependencies)
+- WeasyPrint fallback for compatibility
+- Professional styling with proper sections and formatting
+
+### 📋 **Structured Reports**
+Reports follow the exact terminal structure:
+1. **I. Analyst Team Reports** - Market/Social/News/Fundamentals analysts
+2. **II. Research Team Decision** - Bull/Bear/Research Manager analysis
+3. **III. Trading Team Plan** - Trader's strategic recommendations
+4. **IV. Risk Management Team Decision** - Risk analysts' perspectives
+5. **V. Portfolio Manager Decision** - Final investment decision
+
+### 🎨 **Rich Formatting**
+- Color-coded sections matching terminal output
+- Professional panels and styling
+- Markdown content conversion
+- Responsive layout for different content types
+
+## Usage
+
+The reports module is automatically integrated into the main CLI workflow. No manual intervention required.
+
+```python
+from tradingagents.reports import TradingReportPDFGenerator
+
+# Used automatically in cli/main.py
+generator = TradingReportPDFGenerator()
+pdf_path = generator.generate_pdf(analysis_data, ticker, date)
+```
+
+## Configuration
+
+PDF generation can be configured in `tradingagents/default_config.py`:
+
+```python
+"pdf_generation": {
+    "enabled": True,
+    "output_dir": "results",
+    "page_format": "A4",
+    "margin": "2cm",
+    "font_family": "Arial, sans-serif",
+    "font_size": "12pt",
+    "auto_generate": True,
+}
+```
+
+## Dependencies
+
+- **playwright**: Primary PDF generation engine
+- **weasyprint**: Fallback PDF generation (optional)
+- **rich**: Terminal styling and content formatting
+- **jinja2**: HTML templating
+
+## Output
+
+Generated files are saved to:
+- `results/{ticker}/{date}/analysis_report.pdf` - Main PDF report
+- `results/{ticker}/{date}/analysis_report.html` - HTML backup
+
+Example file sizes:
+- PDF: ~900KB (comprehensive analysis with all sections)
+- HTML: ~45KB (structured content backup)
