Sphinx is a maintained by a group of volunteers. We value every contribution!
The code can be found in a Git repository, at https://github.com/sphinx-doc/sphinx/.
Issues and feature requests should be raised in the tracker.
The mailing list for development is at Google Groups.
There is also the #sphinx-doc IRC channel on freenode.
For more about our development process and methods, refer to Sphinx internals.
