Where help?

Did you need help downloading it in general or installing it on a server? Subscribing and then starting Ark should start the basic installation on your pc. As for putting it on a server, don't have much experience there, but you will need the mod ID 970855993

To OP, you install the same as any other mod.
If you have zero experience at all then this might help.
