First time setup

Booting the game with BepInEx for the first time

With the extraction of BepInEx now finally done, boot your game once, NOTE, THE GAME WILL TAKE WAY LONGER THAN USUAL TO BOOT NOW, THIS IS COMPLETELY NORMAL!

Once your game is finally done booting after a while, close the game and check the following folders.

interop

Open the BepInEx folder inside your game directory, it should have a folder called "interop", inside this folder, there should be a bunch of .dll files, this is completely normal and these were all dumped from the game itself after that initial very long boot.

config

You should also have a config folder with a .cfg file named "BepInEx.cfg", if this file does not exist for some reason, try relaunching the game once more so it generates, if, for some reason, it still does not, here's a default configuration .cfg file that you can place in this directory.
