+    This is a sample Pet Store Server based on the OpenAPI 3.0 specification.  You can find out more about
+    Swagger at [http://swagger.io](http://swagger.io). In the third iteration of the pet store, we've switched to the design first approach!
+    You can now help us improve the API whether it's by making changes to the definition itself or to the code.
+    That way, with time, we can improve the API in general, and expose some of the new features in OAS3.
