1: Go to the game on steam, click the cog icon and click "browse local files (should look something like this: "F:\SteamLibrary\steamapps\common\KingdomComeDeliverance\mods")
2: Create a folder in the game folder titled "mods" (MAKE SURE TO LOWERCASE IT)
3: Get your mod folder and drag and drop it into the mods folder (It should be the folder directly containing a data folder and a manifest.)
4: Rename it to not have any spacebars (preferably one word)
5: Do not make a mod order. Ever.
6: Test it to see if it works.
IT SHOULD LOOK ALONG THE LINES OF THIS:
