I am a student
You should have applied by April 3rd, 19:00 UTC on the Google Summer of Code application.
Familiarize yourself with the communication tools of Debian:
IRC on general or team development channels
the general and particular Mailing-lists of various teams
Join the communication channels of the teams or persons involved with the subject you would like to work on and discuss it. Don't be afraid to suggest seemingly crazy or vague ideas, we'll help you and give you suggestions. If you're lost (or even not!), drop in the communication channels of the Summer of Code team mentioned below. Remember that early preparation is a guarantee that your proposal will be better!
There is some interesting introductory documentation on this wiki about what Debian is and what Debian is for a developer. A lot of information about being a Summer of Code student can be found on the Advice for students page.
We also have a template that we would recommend students to use for their application: application template
I am a Debian developer
Your help is much needed from general organization to individual mentoring. Come see us on IRC or on the mailing-list mentioned below.
