We welcome you to follow, fork, and work on, our open source projects. If you want to contribute back to this project, or any other GitHub project, we need to ask you to complete the Contributor License Agreement (CLA) below. If you are contributing on behalf of your employer, or as part of your role as an employee, remember that you are signing in the name of your employer and you have to make sure that that's okay before you sign.
This is GitHub Inc.'s Contributor License Agreement. If you've worked in the technology space before, contributed or maintained an open source project, there's a good chance that you've run across one or more of these in the past. What CLAs aim to do is make sure the project is able to merge contributions from multiple contributors without getting itself into different types of trouble. This one is no different in that sense.
The answer is that we need to protect the open source projects that we maintain, their users and their contributors (including Hubber contributors, of course, but not just). Why? Just imagine a case when a contributor is making a contribution to a project and that contribution is subsequently merged and becomes an integral part of the project. Now, go on to imagine that our contributor copied the code, or that this contributor works for a company that doesn't want its employees to make contributions to this project or any project. What then? Well, the person the code was copied from or the company can do whatever the hell they like, including to come after the project and its users if using it, make them stop or even sue. If either has patent rights in the code, the project is in even deeper trouble.
Please read the following terms, make sure you understand, and that if you agree, that you sign. Then, your pull request would be created and the project and the other contributors would be safe. It's important to us that you remember that except for the license you grant by signing this document - to GitHub, to your fellow contributors and to the project, you reserve all right, title, and interest in your contributions.
You, you (Your, or your) means the copyright owner or legal entity authorized by the copyright owner to sign this agreement.
Contribution or contribution means any original work of authorship, including any modifications or additions to an existing work, that is submitted to a GitHub project. "Submitted" means via a Pull Request, an issue or any form of electronic, verbal, or written communication sent to GitHub.
Subject to the terms and conditions of this agreement, you grant to GitHub, to fellow contributors and to the project a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute your contributions and such derivative works.
Subject to the terms and conditions of this agreement, You hereby grant to GitHub, to fellow contributors to the project, and to its users a perpetual, worldwide, non-exclusive, no-charge, 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 as part of the project, where such license applies only to those patent claims licensable by you that are necessarily infringed by your contribution or by combination of your contribution with the project to which this contribution was submitted. If any entity institutes patent litigation against you or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your contribution, or the project to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this agreement for that contribution shall terminate as of the date such litigation is filed.
Signing would mean that you are legally entitled to grant the above license. If your employer(s) has rights to intellectual property that you create that includes your contributions, you have verified and are certain that you have received permission to make your contribution on behalf of that employer, that your employer has waived such rights for your contribution, or that your employer has executed a separate license with GitHub or the project.
Signing doesn't change the fact that your contribution is your original creation (see section 7 for submissions on behalf of others) and that they include complete details of any third-party license or other restriction (including related patents and trademarks) of which you are personally aware and which are associated with any part of your contributions.
Signing this won't mean anybody will argue otherwise. In other words, your contributions are made without warranties or conditions of any kind.
That's fine but you need to identify the source or sources of the contribution and any license or other restriction (like related patents, trademarks, and license agreements) of which you are personally aware, and conspicuously marking the contribution as "Submitted on behalf of a third-party or third parties: [named here]". A place where you can do this is in a commit comment to the PR.
You agree to notify the project and GitHub of any facts or circumstances of which you become aware.
