Does anyone know how to change vehicle textures using Wolvenkit?

So i literally started modding for the first time like 15 minutes ago, and i figured out how to change textures on clothing, but it seems more complicated on vehicles, when i look at the xbm files they look very distorted and i have no idea what i'm looking at. Right now i just wanna figure out how to add decals and stickers to the cars. Thanks!
