Hm, I like this document, and I wouldn't mind linking to it as a resource for learning how to write JSON Schemas, but I'm not sure this is the best spot for it. I don't have a better suggestion though so I guess I can live with it. Or well, maybe as a lead-in to this document might work. Missing a plural here too for "schema" (and I think the rest of the docs generally capitalize like I did in this comment).
