readme.rst lacks detail

[taylorbyte]

I gather swarm is kind of new. Other docker formulas are not working out for me including the official docker salt formula. When i read through the readme on this formula i saw "swarm" stuff so it made read up about it and made me want to try it out. But I'm having trouble understanding the pillar examples, do some of them need to be combined? and in what way? how does each pillar example code block relate to each other?
