Howdy! Thanks for supporting this mod; it really means a lot!

To get started, simply extract the file labeled "nativePC" from the zip into your Monster Hunter World main directory.
You'll probably find that folder somewhere around this file path: steamapps/common/Monster Hunter World

To know you're in the right folder, you should see a "chunk" folder and the MonsterHunterWorld application launcher.

Once your files are in place, just boot up your game and try on the new fashion!

This specific mod alters the Thermae Layered helm and body, and the HR Odogaron Beta waist, legs, and arms.
You can put all five armor pieces on as Layered armor, or mix and match as you'd like. Just be sure to set the colors 
to 'default' for the textures to show up properly.

Happy Hunting!
