First of all, thank you for installing the mod! I hope it brings a lot of joy! 

So installing is the same with most sound mods. 



Just copy the data Folder from the Package into your Fallout 4 folder.

If you're unsure where that is, it is usually located in 

C:\Program Files (x86)\Steam\steamapps\common\Fallout 4

or 

C:\Program Files\Steam\steamapps\common\Fallout 4


If you're unsure the easiest way is to just go into steam (if it's steam version) and right click, properties, local files then browse local files 


if you have a desktop shortcut it's pretty much the same, right click, properties, open file location 


Hopefully this is NMM Compatible so you don't need to worry about that at all :D 


Enjoy. Any issue don't hesitate to comment on the mod page, i'll see what i can do?
