[Need help for instal a prefab (french noob)]

Hello everyone , I really need your help please.

I run a 7 day to die server on my computer for my friends and me. We recently discovers mods and we add some of it in the server. But we found a prefab of a castle and we absolutely want it on the server in our game. But I really don't know how to do it.
The bad news is,I am French,and all information are in english.

Can you , please , explain me how to do it with basic english for me to understand ?

Thank you very much and have a nice day.

:D
