# Sphinx development

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, see the Sphinx Developer’s Guide.
