When you download anything, it comes with the item picture files and a item.cfg file. First you put all your pictures in the Feral Heart>Media>Items folder, and in the Feral Heart folder, there should be a item cfg file already in there. Open it up in word and copy and paste all your downloaded coding in there. Regardless of what item pack you get, there is always a item cfg in there cause its what makes the items actually viewable in game
