Want to contribute? Great! First, read this page (including the small print at the end).
Before we can use your code, you must sign the Google Individual Contributor License Agreement (CLA), which you can do online. The CLA is necessary mainly because you own the copyright to your changes, even after your contribution becomes part of our codebase, so we need your permission to use and distribute your code. We also need to be sure of various other things—for instance that you'll tell us if you know that your code infringes on other people's patents. You don't have to sign the CLA until after you've submitted your code for review and a member has approved it, but you must do it before we can put your code into our codebase.
Before you start working on a larger contribution, you should get in touch with us first through the issue tracker with your idea so that we can help out and possibly guide you. Coordinating up front makes it much easier to avoid frustration later on.

Do not submit any code or prose written or modified by large language models or "artificial intelligence" such as GitHub Copilot or ChatGPT to this project. These tools produce code that looks plausible, which means that not only is it likely to contain bugs those bugs are likely to be difficult to notice on review. In addition, because these models were trained indiscriminately and non-consensually on open-source code with a variety of licenses, it's not obvious that we have the moral or legal right to redistribute code they generate.
