I still don't understand where or what are the requirement for the Elin Race Remastered

Hi here i am, new in this world of modding and i fell in love with the elin race mod (from what i've seen in the picture) but there is one problem i can't make it possible i try multiple time and im not even sure to actually have all the requirement because im not really sure where are they or what are they, i know that everything is suppose to be accessible from just the link that you provide in the banner but i still can't get my head around it, could you land me a hand please ?
