Instructions on how to clone and extend

[rob-metalinkage]

Need to leverage template better:

provide instructions on how to clone and extend buildiong blocks in every template - and every generated doc should have this prominently linked.

in general replace schema with a simple scheme of form and start editing examples to test things...

  "description": "My local extension of something",
  "allOf": [
    {
      "$ref": "{href to reused building block schema}.(json|.yaml)"
    }
  ]
}
