Before starting on a patch, first check in our issues `Zephyr Project Issues`_
system to see what's been reported on the issue you'd like to address. Have a
-conversation on the `Zephyr devel mailing list`_ (or the #zephyrproject IRC
-channel on freenode.net) to see what others think of your issue (and proposed
-solution). You may find others that have encountered the issue you're
-finding, or that have similar ideas for changes or additions. Send a message
-to the `Zephyr devel mailing list`_ to introduce and discuss your idea with
-the development community.

-Please note that it's common practice on IRC to be away from the
-channel, but still have a client logged in to receive traffic. If you
-ask a question to a particular person and they don't answer, **try
-to stay signed in to the channel** if you can, so they have time to
-respond to you. This is especially important given the many different
-timezones Zephyr developers live in. If you don't get a timely
-response on IRC, try sending a message to the mailing list instead.
