How to add "examples" to "responses"?

Hi,
I want to add "examples" to the "responses" of each "code". But I did not find any documentation talking about this?

Sample:

The report names no file, test, or entry point, so start by locating the response-generation and documentation code in the repository. Document the supported way to add examples to each response code, with a confirming example or test showing the resulting output.
