## Fiduciary Contributor License Agreement

Before making any contributions, all contributors are required to sign the Fiduciary Contributor License Agreement (FLA). The FLA is a legal agreement that assigns the copyright of contributions to a designated fiduciary, who manages these rights on behalf of the project. This arrangement ensures that the software remains free and open, even as contributors come and go.

Key points of the FLA:

- Ensures the software remains free and open source
- Protects the project from potential copyright issues
- Includes a reversion clause: if the fiduciary violates Free Software principles, rights revert to the original contributors

For more details about FLA, please refer to the [FLA FAQ](https://fsfe.org/activities/fla/fla.en.html).
