Google Summer of Code and Krita

We welcome students who want to work on Krita for Google Summer of Code. If you want to work on Krita, keep in mind that we would like you to stay with the project, also outside Summer of Code. Summer of Code isn't just a summer job with some mentoring added -- it's a way of becoming part of the team. We're also really underpowered at the moment, and we can only take on mentoring students who have a proven knowledge of C++ and Qt.
