IF THIS IS YOUR FIRST FALLOUT 4 MOD THERE ARE SOME ADDITIONAL STEPS REQUIRED TO MAKING
IT WORK PROPERLY, PLEASE GOOGLE THESE INSTRUCTIONS BECAUSE I'M TOO LAZY TO WRITE THEM HERE
==========================================================================================

But if this isn't, then simply extract or drag and drop "Meshes" into the following
directory:
"(DriveLetter):\Steam\steamapps\common\Fallout 4\Data"

If a prompt pops up asking if you want to overwrite folders and files, click "Yes to All".

Enjoy!
