could someone make a guide how to install it ?
i've already downloaded and activated it but where do i find it? o.o

what is that you exactly want?
if it's mod can you link it?
if you mean the racemenu console command it goes like this

thanks!!!!!!! i was searching for the code
btw mate to activate the mod do i always need to enter the code for it?

you wont need the mod for it. you can uninstall it and delete

just open console from § and just type that in
