How does you example fit into a traditional Broccoli config

[dehuszar]

I'm a little new to using Broccoli outside of Ember-CLI. Can you expand your README example to describe where in a typical broccoli setup your example would fit? Just placing your example into a Brocfile is yielding non-descript errors. I'm sure I'm missing a basic step, but I imagine others may benefit from a little extra boilerplate for getting started.
