emacs lilypond-mode

[Thomas]

Hallo, 
I'm new to emacs and lilypond, but I managed 
to set up lilypond mode successfully.

I'm still not able to use it ... 
and I can't find any usefull explanation on how 

to work with emacs lilypond mode in the pdf's
 and not even on the web 
(whats quite amazing). 

Is there any source with infos about emacs 
lilypond-mode? not only the setup, 
but how to use it?

I would appreciate any help.
