We do not want to sound as the Freiherr1) of Knigge2) here. But visitors to the (German) natury website asked for this topic and therefore we have included it to our information service.
What one does:
Be as correct and considerate as usual.
Undress oneself. That's, like all do.
Do not make a fuss about it. That's, like all do.
Look into the face of others. That's, like all do.
Show respect and understanding of individual characteristics. After all, many people are not able to help how they look alike.
What one does not:
No stare at any peculiarities. One does not even do that elsewise.
Do not disturb or bother anyone. That's even not respectable elsewise.
Do not position yourself conspicuously. One is only one among many.
No activities, which are not intended for the public. One does it even do that in the bedroom elsewise.
Sing loudly. You should practice it beforehand and ask other to assess it.
Are there any other rules that should be taken into account in the course of the naturists' life and which could be added to this guide? Then please send a message via the contact form. Thank you!
1) "The German-language title of Freiherr is rendered in English as »Baron«, although the title was derived separately in the two languages. Even in German, a Freiherr is often styled and addressed as »Baron« in social circumstances, although not the official title."
The original distinction from barons was that a Freiherr's land property was allodial instead of a fief.

2) "In Germany, Knigge is best remembered for his book Über den Umgang mit Menschen [en: On Human Relations], a treatise on the fundamental principles of human relations that has the reputation of being the authoritative guide to behaviour, politeness, and etiquette. The work is more of a sociological and philosophical treatise on the basis of human relations than a how-to guide on etiquette, but the German word »Knigge« has come to mean »good manners« or books on etiquette."
