Just download the zips from the button on the moddb page and open the mods folder for vintage story
(this can be found on the start menu by pressing "Mod Manager" then "Open Mods Folder")
just drop em in there and be sure to enable them using the Mod Manager you just opened
a true shame, this was one of the vanilla+ overhaul mods that i could easily see being made into the base game at some point and the VS experience is lessened in its absence. Thank you for all the work you have done @jakecool19
