[tohu-users] questionair to include into larger application

Hi I'm building large application with angularjs. Now I have a need to use a questionair and I've been looking at tohu and decided that this seems a solid framework for the job. The only question is how this will integrate with the rest of my application which is a pure rest based back-end with a angularjs front-end. Any suggestions? Is there also more documentation to be found? Now I'm just engineering on top of the examples to build something I want. Everything works as long as I stay inside the tohu framework, but what if I want to get my multiple choice answers from my database etc?
