Steam deck game modding help

I’m the greenest you could possibly be when it comes to modding,I have no idea how to do any of this stuff and the only mods I’ve ever used were creation club in Skyrim 😭I’ve been trying to mod Skyrim for 8 hours and just can’t figure out all of this confusing stuff, I’ve never used a pc and have been console only my whole life, downloading nexus is confusing and mo2 is even worse. Steam tinker launch won’t work either and I’m completely stuck, I’d love some help about installing vortex and successfully being able to mod my game. I have a steam deck OLED, and it’s brand new. Also not used to posting on Reddit be nice pls:3
