+
+## 🚨 Important Notes
+
+### SEC API Usage
+- **Rate limits**: Respect SEC's 100ms minimum interval between requests

+- **Fallback data**: Generated sample data when external sources fail
+- **Verification**: Always verify critical data from official sources
+
+## 🐛 Troubleshooting
+
+### Common Issues
+
+1. **No stock data available**
+   - Check internet connection
+   - Verify yfinance installation
+   - Try refreshing data
+
+2. **SEC filings not loading**
+   - Check SEC API status
+   - Verify company ticker spelling
+   - Wait for rate limit reset
+
+3. **Chart display issues**
+   - Update matplotlib and mplfinance
+   - Check browser compatibility
+   - Clear browser cache
+
+### Error Messages
+- **Rate limit exceeded**: Wait and retry
