Step 1. Download the mod
Step 2. Go to your Night of Revenge folder, and click on the "BepInEx" folder.
Step 3. Once you're in the "BepInEx" folder, find and click on the "plugins" folder.
Step 4. Once you're in the "plugins" folder, take the file called "NoREroMod.dll" from the mod folder that you downloaded during step 1, and put it in the aforementioned "plugins" folder.
In the mod folder that you downloaded during step 1, there's also a file called "NoREroMod_README.md". You can safely ignore it.
Step 5. Play the game. This will create the config file for the mod.
If you want to change the mod's settings:
Step 1. Go to your Night of Revenge folder, and click on the "BepInEx" folder.
Step 2. Once you're in the "BepInEx" folder, find and click on the "config" folder.
Step 3. Once you're in the "config" folder, find and click on the file called "NoREroMod". This is the config file for the mod.
Now the "NoREroMod" config file should be open, just like any other text document.
Step 4. Change the settings of the mod to your liking. After you're done, just close the file using the big "X" button.
If you're not sure what the setting that you're changing does, maybe it's better not to touch it for now.
