• show content-type headers

Hey @CastixGitHub!

I would like to use your improvements in my project, but can't get it included in the conf.py properly.
Could you explain how to substitute the extension with your version?

Thank you in advance,
Sue

hi @sommerlilie there's no need to tweak conf.py
just add 'sphinxcontrib.openapi', to the extensions.

did you set up the options from the rst source file?
eg:

.. openapi:: ../specs/main.yml
   :request:
   :group:
   :examples:

[CastixGitHub]

also tell me if you need other authentication methods, i'll be happy to add them too

@CastixGitHub would you be able to rebase this and resolve the conflicts? I'd be happy to get this merged for you.
