add dependencies details

I see @dominictarr has an open PullRequest which links out to details. 
I found it a little inconvenient and missed things first time (I still may be missing things because npm pack isn't working for me yet)

I also wonder if a recommended version of Node / IOJS would be nice here ... I saw references to a range of versions like `> Nodev0.12`, and  `= IOv2.5.0` . Would be good to know if there is anything tricky that needs to be known there
