+Compatibility
+-------------
+If you want to run against the Boreas model runner you must set the URL to end
+with /model/methods/detect. The key is that in Boreas release the model runner
+api has changed. You can see the swagger for the model if you visit the source
+model's swagger.
+
+If you have a model that was onboarded using Athena release you do not need
+the /model/methods check. Use /detect instead. Another change that was made
+in Boreas model runner was that you must send the http headers before the
+default was protobuf. These headers will change automatically when use use
+/model/methods/detect as the URL path.
