12The Mozilla community prides itself on being an open, accessible, and
13friendly community for new participants. If you have any difficulties
14getting involved or finding answers to your questions, please `come and
15ask your questions in our
16chatroom <https://chat.mozilla.org/#/room/#introduction:mozilla.org>`_,
17where we can help you get started.
18
19We know even before you start contributing that getting set up to work
20on Firefox and finding a bug that's a good fit for your skills can be a
21challenge, and we're always looking for ways to improve this process: making
22Mozilla more open, accessible, and easier to participate with. If you're
23having any trouble following this documentation, or hit a barrier you
24can't get around, please join us in the the Introduction room on Matrix
25or contact Mike Hoye directly at mhoye@mozilla.com.
