A: Repentance+ has its own mods folder located here: C:\Users\YOURUSERNAME\Documents\My Games\Binding of Isaac Repentance+\mods however, it is empty. Mod creators will need to update their mods for compatibility. If you copy Repentance or AB+ mods into this folder, you DO SO AT YOUR OWN RISK as things are likely to break."

How do they update it? Since its not downloading and not working

I was able to get Mods to work.

- Go into your steamapps common game folder. In my case it was C:\Program Files (x86)\Steam\steamapps\common\The Binding of Isaac Rebirth\.

- Open the mods folder and copy the mod you want. Double check on steam that the mod has been updated recently or it might cause problems.

- Navigate to Isaac in your My Games folder, in most cases it'll be in C:\Users\Username\My Games\The Binding of Isaac Rebirth.

- Open the Mods folder and paste the folders you copied from steam mods.

- Start up your game and they should be good to go.

Hope this helps.
