Contributing

This kernel is free software and we welcome contributions of any form. Below is a list of possible things you could help with, or you could just scratch your own itch, that's just fine.

There's a number of ways to get your changes into the kernel code. One of those is to send us a pull-request, and then send this to us in the google group/ mailing list. Of course you can also format patches and send those in to the same group.

Github pull requests might work for some projects, but in order to keep the development in a central place, the preference goes out to patches and pull requests in the google group mailing list.
