#markdown_render(only: nil, except: nil) ⇒ Object

Declares that this controller supports markdown responses. With no arguments, this is a semantic label only — the global around_action already handles all markdown requests. Pass ‘only:` or `except:` to restrict markdown conversion to specific actions.
