advice on starting a criminal justice/criminology rso?

hi all!! i’m excited to get involved with some organizations on campus as a CJ major this year but was really surprised to find that despite having over 700 RSOs there isn’t a single criminology/criminal justice related club or organization (besides alpha phi sigma and the one CJ fraternity)— so i’m looking into starting a club for criminal justice and criminology! if anyone has any advice on starting an RSO, that would be awesome😁
