I am planning on opening sourcing a project that I've been working on for a while and that I think would benefit the community. I've already cleaned up the code, added a reasonable license, and wrote a packaging script for it that runs the unit tests, etc (it's Python, so that means setup.py). I wrote a README that describes the project, my motivations for writing the library, and the basics of how to use it.
What else is expected of me? Is hosting it on GitHub enough or is it expected that I maintain the PyPI packages too? What about testing it with other versions of libraries (I just defined the dependencies as the versions that I use)? What are some nice-to-haves that people really appreciate?
