Dask is a community maintained project. We welcome contributions in the form of bug reports, documentation, code, design proposals, and more.
For general information on how to contribute see https://docs.dask.org/en/latest/develop.html.
Some of the tests require a functioning job scheduler. For more information on how to set this up see https://jobqueue.dask.org/en/latest/develop.html#test-with-job-scheduler.
