The first release of the Expanded Nations mod for HOI4.
The folder that stores mods for the game is
Windows: ...\Documents\Paradox Interactive\Hearts of Iron IV\mod\
GNU/Linux: ~/.local/share/Paradox Interactive/Hearts of Iron IV/mod/
Mac: ~/Documents/Paradox Interactive/Hearts of Iron IV/mod/
Manually downloaded mods should include a .mod text file along with a folder.
If so, the files can simply be dropped into the mod file.
If one is downloading a newer version of a mod they already have installed, one should remove the older files first
If there is any trouble with installation visit here: Hoi4.paradoxwikis.com
If there's any problem with the mod, don't hesitate to let me know.
