The project currently does not accept pull requests as it is still early-stage, but we plan to allow contributed algorithms and benchmarks in the future. We are also always very happy to get your feedback via issues!
Contributions to this project must be accompanied by a Contributor License Agreement (CLA). You (or your employer) retain the copyright to your contribution; this simply gives us permission to use and redistribute your contributions as part of the project.

You generally only need to submit a CLA once, so if you've already submitted one (even if it was for a different project), you probably don't need to do it again.
