In the process of learning/implementing k2 I started documenting my experiences. I've made a pdf document available and attached it here. It is by no means authoritative, in fact it will no doubt have a number of errors. It may however help 'real noob's' wrap their heads around a component that, in the beginning can look quite daunting. I hope it is of assistance to some of you out there. Is there a Wiki for k2 somewhere that we could have users contributing to?
