BepInEx Setup
If BepInEx has already been installed, skip this section.

Download BepInEx from https://github.com/BepInEx/BepInEx/releases/download/v5.4.22/BepInEx_x64_5.4.22.0.zip

* Extract the contents of the BepInEx zip file into the game's directory:

    __Important__:  The .zip file *must* be extracted to the root folder of the game.  If BepInEx was extracted correctly, the following directory will exist: <Steam Directory>\steamapps\common\Card Survival Tropical Island\BepInEx.  This is a common install issue.
* Run the game.  Once the main menu is shown, exit the game.
    
* In the BepInEx folder, there will now be a "plugins" directory.

Mod Setup
* Download the ViewMoreCards.zip.  
    * If on Nexumods.com, download from the Files tab.
    * Otherwise, download from https://github.com/NBKRedSpy/CardSurvival-ViewMoreCards/releases/
* Extract the contents of the zip file into the BepInEx/plugins folder.
* Run the Game.  The mod will now be enabled.
