   Return the JSON representation of the blueprint. This includes 3 top level
   objects.  `changes` which lists whether or not the workspace is different from
   the most recent commit. `blueprints` which lists the JSON representation of the
   blueprint, and `errors` which will list any errors, like non-existant blueprints.
 
-  Example::
+  By default the response is JSON, but if `?format=toml` is included in the URL's
+  arguments it will return the response as the blueprint's raw TOML content.
+  *Unless* there is an error which will only return a 400 and a standard error
+  `Status Response`_.
+
+  If there is an error when JSON is requested the successful blueprints and the
+  errors will both be returned.
+
+  Example of json response::
