There wasn't really any single resource I read. Frustratingly, I find it quite difficult to read research papers (I'm told it's a skill acquired with practice, but it's something I've never gotten into). Most of the implementation is the product of several rewrites and false-starts, along with the occasional hint I've read about here or there on the web.
Ah, a trail of even just the web articles you read that was helpful would be helpful, as part of people looking to Tao for inspiration. Consider writing them down in the wiki part of the repo as you go along going forward!
