I like this idea, but the barrier to entry to working with Mixco is quite high. The way the documentation is now requires a strong background in Node, JS, CoffeeScript, and Mixxx's mapping formats to know where to start. The documentation for each of Mixco's modules is pretty good. But what I think is missing is a general overview tutorial that explains how to start working with Mixco from the beginning and how the different parts of Mixco work together.
I agree that such tutorial should be added.
