## Summary | 摘要

| Component | License | Commercial Use | Modification | Distribution | Patent Use |
|-----------|---------|----------------|--------------|--------------|------------|
| Documentation | CC BY 4.0 | ✅ Yes | ✅ Yes | ✅ Yes | N/A |
| CLI Tool | MIT | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |

Both licenses are permissive and allow commercial use. The main difference is that MIT is specifically designed for software and includes explicit patent grants, while CC BY 4.0 is optimized for creative works and documentation.

兩種授權都是寬鬆型授權，允許商業使用。主要差異是 MIT 專為軟體設計並包含明確的專利授權，而 CC BY 4.0 則針對創意作品和文件優化。
