# Contributor License Agreement Thank you for contributing to Zelyq. Before a contribution can be merged, we need you to agree to this Contributor License Agreement (the "Agreement"). It lets the project accept your work while keeping the freedom to license Zelyq under the GNU Affero General Public License v3.0 and a commercial license at the same time. You accept this Agreement by adding a `Signed-off-by` line to your commits (see below) and confirming acceptance when prompted on your first pull request. If you are contributing on behalf of an employer, make sure you are authorised to do so. ## Terms 1. **Definitions.** "You" means the individual or legal entity making a Contribution. "Contribution" means any original work of authorship — code, documentation, or other material — that you intentionally submit to this project for inclusion. 2. **Copyright license.** You grant Dee Empire and recipients of software distributed by Dee Empire a perpetual, worldwide, non-exclusive, royalty-free, irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute your Contribution and derivative works. This includes the right for Dee Empire to license your Contribution under the GNU Affero General Public License v3.0, the Zelyq Enterprise License, and any other license terms, including proprietary and commercial terms. 3. **Patent license.** You grant Dee Empire and recipients of the software a perpetual, worldwide, non-exclusive, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer your Contribution, where such license applies only to patent claims licensable by you that are necessarily infringed by your Contribution alone or by combination of your Contribution with the project. If any entity institutes patent litigation alleging that your Contribution, or the project to which you contributed, constitutes direct or contributory patent infringement, any patent licenses granted under this Agreement for that Contribution terminate as of the date such litigation is filed. 4. **You retain your rights.** You keep all right, title, and interest in your Contribution. This Agreement is a license, not an assignment; nothing here prevents you from using your Contribution for any other purpose. 5. **Your representations.** You represent that each Contribution is your original creation and that you are legally entitled to grant the above licenses. If your employer has rights to intellectual property you create, you represent that you have permission to make the Contribution on behalf of that employer, or that the employer has waived such rights. If any part of your Contribution is not your original creation, you will identify it, its source, and any license or other restriction you are aware of. 6. **No obligation.** You understand that the decision to include your Contribution is entirely at the discretion of the project, and this Agreement does not obligate the project to use it. 7. **No warranty.** Except as stated above, the Contribution is provided "as is", without warranty of any kind. ## How to sign off Add this line to every commit message (Git adds it automatically with `git commit -s`): ``` Signed-off-by: Your Name ``` By signing off you certify the origin of the Contribution under the [Developer Certificate of Origin 1.1](https://developercertificate.org/) **and** agree to the terms of this Agreement for that Contribution.
