Inside the folder where you can see the “Mod Examples” folder there should also be a folder named “Mods”.
Inside the “Mod Examples” folder is another folder with the unit’s name. You need to take this unit folder out of the “Mod Examples” folder and put it in the “Mods” folder.
After that, launch the game as normal and the game will load the mod. This process is the same for installing any character mod.
