Document protecting path with roles

[ipeychev]

Protecting given path with roles have to be added to the documentation. Here is an example:

{
  "data": true,
  "path": "/",
  "auth": {
    "scopes": ["admin"]
  }
}

Documentation has moved to a new repository (https://github.com/wedeploy/wedeploy.com), if this issue is still valid would you mind moving it over there? Thanks!
