Seems interesting but there isn't enough background on what this is. Just a collection of components, or is there anything custom added on top of the collection of frameworks? The BTC website is pretty bad too, coming from someone who doesn't already know what all those different frameworks do. There is no sample code or "getting started" guide to illustrate what the project does or why I would want to use it. Especially curious about why I'd want this template over others? What are the competitors/alternatives?
