JSON Schema Documentation Generators
I found a hit that works very well. https://github.com/bootprint/bootprint-json-schema is a node module that has the perfect system.
There is also PRMD, although I think it has similar limitations: https://github.com/interagent/prmd
Hopefully with JSON Hyper-Schema draft-07 about to be published, there will be a new generation of API documentation systems to follow.
https://github.com/adobe/jsonschema2md - As it's name suggests, generated Markdown from JSON Schema files.
