Describe how to join PlasmaPy effort as a participating project

It would be helpful for our website (or perhaps documentation) to describe how a research group or experiment can officially become a participating project. This would effectively be a partnership, with responsibilities shared between the core developers and the participating project.

We should describe what it means to be a participating project, including what the responsibilities of the participating projects are. Some possibilities:

• Appoint one or two people to be representatives for the project to PlasmaPy [who will ask us questions, answer questions from us, request features, (preferably) contribute code/docs/tests now and then, share knowledge with the rest of their team, etc.]
• Create use cases specific for their project to help us collaboratively design workflows
• A commitment to develop (especially experimental or simulation) analysis software to be compatible with PlasmaPy over next few years (though not necessarily all of their software)
• Participate in planning discussions on the future of PlasmaPy

We should also describe what those of us on the NSF CSSI grant will be responsible for (i.e., user support, developer support, providing trainings, quick/constructive code reviews, etc.).

These are initial thoughts, so suggestions on how we should go about this are welcome!

Start by reviewing the existing website and documentation to find the appropriate place for information about participating projects. Define what participating projects and the NSF CSSI-supported PlasmaPy team are responsible for, including representatives, collaboration, support, training, and contributions; the documentation is done when these expectations are clearly described.
