For your own organisation, consider putting them inside folders, eg: plugins/ActualRain/ActualRain.dllīepInEx/patchers - These are more advanced types of plugins that need to access Mono.Cecil to edit. If a mod is just a NAME.dll file, it probably goes in here. The zip looks like: \BepInExPack <- move the contents of this folderīepInEx/plugins - This is where normal mods/plugins are placed to be loaded. To install, extract contents of the inner BepInExPack to the gamefolder, such that the winhttp.dll file sits right next to RiskOfRain2.exe. This is the pack of all the things you need to both start using mods, and start making mods using the BepInEx framework.
