# Chapter 31. Contributing

This document, like so much other great software out there, was created for free by volunteers. If you are at all knowledgeable about any aspect of gtkmm that does not already have documentation, please consider contributing to this document.

Ideally, we would like you to provide a patch to the `docs/tutorial/C/gtkmm-tutorial-in.xml` file. This file is currently in the `gtkmm-documentation` module in GNOME git.

If you do decide to contribute, please post your contribution to the gtkmm mailing list at <gtkmm-list@gnome.org>. Also, be aware that the entirety of this document is free, and any addition you provide must also be free. That is, people must be able to use any portion of your examples in their programs, and copies of this document (including your contribution) may be distributed freely.
