What is a License
An open source license is a legal agreement that authorizes others to use, modify, and distribute your code. Choosing the right License protects your rights while clarifying boundaries for others using your code.
License Categories

- Weak Copyleft：Modifications to the library itself must be open-sourced, but can be linked by closed-source projects
- Strong Copyleft：Derivative works from modifications must be open-sourced under the same license, suitable for projects emphasizing open sharing
