1. Setup

1. Add references to WKLib.dll (found here) and ImuiBepInEx.dll (found here).
2. Make sure your plugin imports the WKLib namespace (using WKLib.API;)
3. Add WKLib as a hard dependency, like so

using BepInEx;
using WKLib.API;

[BepInDependency(WKLibPlugin.GUID, BepInDependency.DependencyFlags.HardDependency)]
public sealed class Plugin : BaseUnityPlugin
{    
	// your plugin
}
