This is EZ

You take this file... it's called ... uhm ... OH ! "RenasSmithingMod.esp" and put it into your

SKYRIM/DATA Folder ... Okee ?

Might be located somewhere around ... Steam\SteamApps\common\Skyrim\Data ... or so, not sure ...

I am sure you will find it ! If not, Google is your friend !

Then activate it in the skyrim launcher or over a mod organizer and you are done, have fun.

Regards Dolan ... no ... R E N A ! Have fun !
