How to install mods on your ARK Survival Evolved server

Mods enhance your server. You can find an overview of all available mods in the Steam Workshop
All you need to install a mod is the Workshop ID.
You can find this ID in the mod’s URL.
In the case of Structures+ https://steamcommunity.com/sharedfiles/filedetails/?id=731604991, the Workshop ID is 731604991.

Once you have the ID, you can easily install mods through the web interface.

If your server is in Basic mode

Mod Settings -> Modifications
Simply enter your mod IDs here (comma-separated)

If your server is in Advanced mode

Server Settings -> GameUserSettings.ini -> ActiveMods=
Simply enter your mod IDs here (comma-separated)
For example, ActiveMods=731604991
Click Save and restart the server.
