The generated code package docs exports SwaggerInfo variable which we can use to set the title, description, version, host and base path programatically. The path parameter cannot be added to the comments of the endpoint, instead a new struct needs to be defined: Fortunately, the UUID path parameter can be reused for multiple operations including the update-thing and delete-thing operation. One such usage is in method names for client generation for example. What is the best way to show results of a multiple-choice quiz where multiple options may be right?

And I want to add new handler to serve my own UI files.
