Well you do need to be a little bit of a programmer. You have loops in there, and evaluating properties of objects, etc. Interesting idea and it looks like you've done a nice job of it.
You don't really need to use those templates at all. What those templates do is let you do advanced stuff like client-side rendering, dynamic data processing, etc.
But you can build a full fledged app WITHOUT any of those advanced stuff. Watch the video on the website and you'll get it immediately!
