   Handles large datasets efficiently with intelligent parsing and optimized date recognition.
 
+## 💡 Use Cases & Examples
+
+### Log Analysis
+
+Extract timestamps from application logs to analyze patterns:
+
+```json
+// Extract from app.log
+{
+  "timestamp": "2023-12-25T10:30:00Z",

+  "message": "User login successful",
+  "userId": "12345"
+}
+```
+
+### API Response Analysis
+
+Analyze date patterns in API responses:
+
+```json
+// Extract from api-response.json
+{
+  "createdAt": "2023-12-25T10:30:00.000Z",
+  "updatedAt": "2023-12-25T15:45:30.000Z",
+  "expiresAt": "2024-01-01T00:00:00.000Z"
+}
+```
+
+### Database Record Analysis
+
+Extract dates from database exports:
+
+```csv
+// Extract from users.csv
+id,name,created_at,last_login
+1,John Doe,2023-01-15 09:30:00,2023-12-25 14:20:00
+2,Jane Smith,2023-02-20 11:45:00,2023-12-24 16:30:00
+```

+### Performance Notes
+
+- **Memory Usage**: ~50MB base + 1MB per 1000 dates processed
+- **Large Files**: Files over 50MB may show reduced throughput (200K-800K dates/sec)
+- **Timezone Analysis**: Adds 20-30% processing time when enabled
+- **Date Parsing**: Complex date formats may reduce throughput by 50%
+- **Hardware Requirements**: Minimum 4GB RAM, recommended 8GB+ for large datasets
+
+## 🔧 Troubleshooting
+
+### Common Issues
+
+**Extension not detecting dates**
+
+- Ensure file is saved and has a supported extension (.json, .yaml, .csv, .js, .log)
+- Check that `dates-le.enabled` is set to `true` in settings
+- Try reloading VS Code window (`Ctrl/Cmd + Shift + P` → "Developer: Reload Window")
+
+**Performance issues with large files**
+
+- Files over 10MB may take longer to process
+- Consider using `dates-le.includeComments: false` to reduce processing time
+- Enable `dates-le.sortByFrequency: false` for faster extraction
+
+**Dates not appearing in results**
+
+- Verify the date format is supported (ISO 8601, RFC 2822, Unix timestamps)
+- Check if `dates-le.extractIso`, `dates-le.extractRfc2822`, etc. are enabled
+- Ensure dates are not inside comments if `dates-le.includeComments` is disabled
+
+**Timezone analysis issues**
+
+- Enable `dates-le.timezoneAnalysis: true` for timezone insights
+- Check that dates include timezone information for accurate analysis
+- Some date formats may not support timezone analysis
+
+**Extension crashes or freezes**
+
+- Check VS Code version compatibility (requires 1.85.0+)
+- Disable other date-related extensions temporarily
+- Check Output panel → "Dates-LE" for error messages
+
+### Getting Help
+
+- Check the [Issues](https://github.com/nolindnaidoo/dates-le/issues) page for known problems
+- Enable telemetry logging: `dates-le.telemetryEnabled: true`
+- Review logs in Output panel → "Dates-LE"
+
+## ❓ FAQ
+
+**Q: What date formats are supported?**
+A: ISO 8601 (2023-12-25T10:30:00Z), RFC 2822 (Mon, 25 Dec 2023 10:30:00 GMT), Unix timestamps (1703508600), and common date patterns (12/25/2023, 25-12-2023).
+
+**Q: Can I extract dates from comments?**
+A: Yes, enable `dates-le.includeComments: true` to include dates found in comments and documentation.
+
+**Q: How does timezone analysis work?**
+A: When `dates-le.timezoneAnalysis: true` is enabled, Dates-LE analyzes timezone information in dates and provides insights about temporal data distribution.
+
+**Q: Can I group dates by format type?**
+A: Yes, enable `dates-le.groupByFormat: true` to organize results by date format (ISO, RFC, Unix, etc.).
+
+**Q: Does Dates-LE work with log files?**
+A: Absolutely! Dates-LE is perfect for analyzing log files, API responses, and temporal datasets to identify patterns and anomalies.
+
+**Q: What's the largest file size supported?**
+A: Dates-LE can handle files up to 200MB, though performance may be reduced for very large files. Consider using streaming mode for large datasets.
