How do you guys adding overview section?

I'm working on an API service, which have some endpoints are handled by third-party libraries(e.g: Laravel Passport) and have a general error format that should be output to the final blueprint document.

I want to place an overview section before main content like this:
https://github.com/apiaryio/api-blueprint/blob/master/API%20Blueprint%20Specification.md#def-api-name-section

Sadly, it seems not supported by `dingo/blueprint`, so I create a new controller, define several empty methods to output these documents.

Is there anyway that I can insert contents as overview section into the blueprint document?

Compare the requested overview section with the linked API Blueprint specification, then inspect dingo/blueprint's document-generation entry points and the controller approach described in the issue. Determine whether the generated document can include overview content and a general error format before its main content; done means both appear in valid Blueprint output.
