This is easier for me.

mock.json

{
  "type": "body",
  "attrs": [],
  "children": [
    {
      "type": "navbar",
      "attr": {
        "inverse": true,
        "title": "scribe",
        "elements": [
          "Home"
        ]
      },
      "children": []
    },
    {
      "type": "container",
      "attr": null,
      "children":  [
        {
          "type": "jumbotron",
          "attr": {
            "heading": "Introducing Scribe",
            "subheading": "Turn any picture into a fully-functional website."
          }
        }
      ]
    }  
  ]
}
