Mod add some useful features to dedicated server:
First of all if you want to use discord features you need to create your discord bot and invite it on your server (pick bot and applications.commands scopes).
Install all dependencies on your server. Unpack servertools.dll and servertools.VIPlist.txt to the VRising_Server\BepInEx\plugins folder.
Start the server, the mod will create an empty configuration file.
Turn off the server and edit the file \VRising_Server\BepInEx\config\neanka.servertools.cfg
Start the server again. That's it.
