welcome to the forum

but
english please
even if it's just a
google translation or something, we can work with that;
if we (mods) see cyrillic, we assume spam

(and we have to use a translator as well)
to your question (roughly "is the mod-installation the same as in Skyrim?"):
yes, it's the same.
but please be careful with that; mods could easily break you game
