Foulproof guide for Skin System

[consiefe]

Can anyone who knows how to build the file structure for Hook5 Universal Skin System create a foulproof guide from the begining to the end of the process for the likes of me who can not make it work please? 

 

I have the paid hook5 and doing what I'm being told but can't make hook5 pick my skins. And I downloaded tattoo layers and packs, can't use genital tattoos as they don't appear in customiser. There are many people who gave up on this, I hope someone put an end to that. Thanks in advance.
