Noobs question about using transmog mod
So I'm playing Nordic soul and want to add transmog mod: https://www.nexusmods.com/skyrimspecialedition/mods/174356.
I place my transmog mod above Water for ENB (Shades of Skyrim).esp
people on Discord say that "When adding mods, it's IMPERATIVE that you should check them in xEdit for conflicts or errors." But I don't know much about modding xEdit or anything like that. Can someone give me advises?
