Template:Volunteer Intro
Many people think that contributing to the FlightGear project requires writing C++ code or doing 3D modeling and that it takes lots of time, and therefore feel that they cannot contribute directly. Not so. There's a whole variety of ways to make a valuable and satisfying contribution to FlightGear without being a developer.
The Volunteer page is intended to provide a starting point for those wanting to contribute, but who don't know how. Of course, these are just suggestions. So if you have already a specific idea in mind, please do get in touch with the community to ask for feedback, using the mailing lists, forum 
or the IRC channel (chat).
Remember that work in non-development areas will be appreciated as much as developer contributions (or more!), because generally more visible to the end user.
If you'd like to learn more about getting your own ideas and features into FlightGear, check out Implementing new features for FlightGear.
If you are contributing to the core simulator, or an aircraft in the master repository, you should be part of the FlightGear-devel mailing list, which is the primary point of contact for all discussions regarding the development of the simulator. You may want to check out also Howto: Understand the FlightGear development process and Howto: Starting core development.
