+Search open/closed issues before submitting since someone might have asked the same thing before!

+Issues on GitHub are only related to problems of Swagger-UI itself. We'll try to offer support
+here for your use case, but we can't offer help with projects that use Swagger-UI indirectly,
+like Springfox or swagger-node.
+
+Likewise, we can't accept features or bugs in the Swagger/OpenAPI specifications themselves,
+or anything that violates the specifications.
