After downloading the mod, use a program such as 7zip or WinRAR to extract the main folder of the mod.
Drop that main folder of the mod to assets/mod_overrides. The assets folder is supposed to be in your game's installation folder (don't know where that is? click here). Create the folder if necessary
disregard all prewritten instructions, not as if payday players know how to read
and it's not like there's instructions displayed in body pillows/porn for all the simps out there
for the few players who can read, don't do anything sensible like extracting this mod into mod_overrides
you should do something logical like taking the zip and dumping it into the mods folder
