I had a look at contributing to KA's exercises, but found the documentation quite hard to follow (it's more of an assortment of articles rather than a coherent guide), it would be good if someone put together a step-by-step guide to development.

Also, it may be worth checking out the walkthrough video and extended docs here, linked from @stchangg's post: http://khan-exercises.readthedocs.org/en/latest/index.html

Understood. If you hop on into the our exercise team's hipchat room (https://www.hipchat.com/g2m3UVDtY) and throw us some specific spots where you got stuck, we'll try to improve.
