To install

Manually copy all the files to the game's Data folder. Don't use FOMM's package manager. Also I notice FONVedit is around now so please never use MasterUpdate on this mod. I've included the esp file for you for editing purposes but the esm is the best to use in game.

Also if you haven't already you will need to go to your Fallout.ini file (in your My Games FalloutNV folder usually) and find the file bLoadFaceGenHeadEGTFiles and change it from 0 to 1. Simples! (As always I was struggling but NosRhyfelwr rode in and sorted it)

Load Order:

Bernie's mod must be loaded after the NCCS Companion System mod esm

There shouldn't be any conflicts unless you have another companion who is placed at Nipton General Store. I deliberately picked there because I don't think others will. She has her own race, her own body files and armor, her own hair and her own dialogue and package options so she shouldn't conflict with anything else.

I say again, don't use MasterUpdate and manually copy all files
