DC Chapter rules for protesting is a good guide.

I did a search to see what those were:

D.C. Chapter’s rules for protesting - No violence, no profanity, no racism, no threats, no provocations, obey the law and treat all law enforcement officers with respect.

I’m not sure if this a complete list but certainly covers most of the bases.
