How to manually install Mods downloaded of Nexus Mods into steamapps/game directory

[Bosn28]

I am a big time gamer but do not speak tech or coding. I downloaded Mods for an unsupported game Disidia Final Fantasy NT. I have read several forums on how to try and manually install the Mods in my games directory through steam local files on C:x86/steamapps/common/DissidiafinalfantasyNT on  drive I manually extracted and put the Mods in the game directory page, that didn't work so I created a Mods folder put the Mods extracted files in the folder didn't work, I took all the extracted files and put it in a folder named common which had tiny little pages with tons of letters and numbers, all the extracted files still didn't work I also downloaded and added the DFFNT_Patcher which is needed to use the Mods, I extracted the files again and it went into the DFFNT_Patcher folder as recommended by the computer the Mods still haven't worked. I desperately need a modder to guide me through installing these Mods manually. I have requested Nexus Mods to add DFFNT as a supported game so I can just dow the Mods through Vortex and let Vortex do it's thing and make sure the Mods are put in the game directory folder correctly so I can use these Mods. Any help would be greatly appreciated I have been trying this for the past 3 days.
