Customization of Swagger while using Plumber is possible?

using plumber I have plumbed my api on a virtual machine now I wanted to customize the swagger interface,is it possible from the same code.

What specific customizations are you trying to do? You can use plumber annotations (#* @apiTitle or something like it) to customize Swagger to a certain extent (ie adding parameter types and definitions). Depending on what you're trying to do, this may be sufficient.

Could you point me to the documentation of the supported plumber annotations?
