How To Add Mod Assistant 

Download the newest Mod Assistant installer from the release section Here and run it. This application auto-updates when launched, there is no need to download a new release each time.

1. Run the game at least once before trying to mod the game! This applies to reinstalling your game too. All mods are moved into an Old X.X.X Plugins folder on first launch to avoid version mismatches, so make sure to do this before installing mods on a fresh version.
2. Once that's done, simply check off the mods that you wish to install and click the Install or Update button. Likewise, click the Uninstall button to remove any mods.
3. Mods are installed to IPA/Pending until the game is run. Boot the game to complete mod installation.
