[translations] new to list

[Malte Meyn <lilypond@xxxxxxxxxxxx>]

Hi list,

I would like to translate some of the documentation to German. For 
start, I’d prefer something not too big, maybe changes.tely as 2.20 is 
to be released soon? How should I start, simply read the contributors 
guide or is there anything else to know?

Cheers,
Malte
