A Contributor License Agreement (CLA) is a legal agreement between a person or organization contributing to a project and the project maintainers. The purpose of the CLA is to ensure that the contribution is made with the understanding that the copyright license granted to the project for the contribution is irrevocable, and to protect the project and its users from legal issues that may arise from the contribution.
The CLA typically includes terms such as the scope of the contribution, the grant of license, the contributor's representations and warranties, and the requirement that the contributor indemnify the project and its users in the event of any third-party claim arising from the contribution.
By signing a CLA, a contributor agrees to the terms and conditions set forth in the agreement, which helps to ensure that contributions are made in compliance with applicable laws and regulations, and protects the project and its users from legal disputes.
