How do I implement Custom Races?

[Geneaux]

I'm having difficulty trying to understand how exactly to utilize the Custom Races mod so that any character I create is entirely unique and different from npcs. I know that data/meshes/CustomRaces/ and data/textures/CustomRaces/ files have to be overwritten but I can't figure which files. I'd say the primary reason for my incomprehension is the file naming and structure. Even looking at it closely, I'm simply lost as to 'what' goes 'where'. The current mods I'm attempting to use with CustomRaces is ADEC, a compatible skeleton(of course), TBBP, new textures, and compatible armor/clothing mods.

 

I use Mod Manager to manage my mods.
