## Testing Strategy
1. **Start Simple**: Begin with the basic examples and ensure they work
2. **Progressive Complexity**: Move to more complex examples
3. **Edge Cases**: Test with different configurations and edge cases
4. **Real-world Scenarios**: Test with actual applications like Nextcloud and Plane
5. **Performance Testing**: Measure resource usage and optimize as needed
## Adding New Examples
When adding new examples, please:
1. Categorize by difficulty level
2. Include a brief description
3. List key features
4. Ensure the example is complete and runnable
5. Add any necessary environment variables or setup instructions
## Contributing
Contributions of additional examples are welcome! Please ensure that any contributed examples:
- Are well-documented
- Follow best practices
- Include all necessary configuration
- Are tested and working
