Workflow using HMR

I could of weeks ago, I was looking for any site that would give a more through understanding of the JSON schema and better understanding of how to clearly make use of representing myself. I had found a site with someone had went above and beyond in automating the process and making things a little clearer. I thought that I had book marked the site and figured I would make my way back. Needless to say, it didn't get saved.

Does anyone know of a site that gives more practical information that they know?
