Well, sorry to tell you but at this point that is all there is. My suggestion to you until there is official documentation is to play around with K2 by inserting sample content and trying out all the options to see what they do. Once you play around with it a bit it will all start to make sense and then you can shape and mold the content how you see fit. There are a ton of options on how to display content, so just choose what is right for your use. Take your time, have some patience. If you truly get stuck and need help, come back to the forums and Im sure I or someone else can try to help you. Good Luck. This is a great product but it's still in its infancy in terms of support and knowledge base.
