Adding more ped models/variants to police uniforms

Hi, my name is Moonah. I’ve recently got my own “Home Hosted” server up and running and have been fooling around with scripts/vehicles. I started a couple months ago, messing around with cars/peds. I’ve recently become better at making liveries and ped uniforms. I’m working on something big now that involves multiple variants of the ped models itself and uniforms. I’m stuck on what to do. I’ve learned that “Meta Toolkit” is what i’ll need to be using. So If someone would be willing to correct me If i’m wrong or tell me the steps I need to take on adding different uniform/ped variants. i’d really appreciate it. If you need to get in contact with me I’m always available to use discord/teamspeak or whatever. Thanks - Moonah
