I tried the following code but it doesn't work.

(advice-add 'describe-mode
            :around 
            #'(lambda () (delete-other-windows) ad-do-it)
            )

Worse still, it brings up the following message when I try C-h f describe-mode 
RET

:around advice: No documentation

Where do I add the documentation to the advice mechanism?
