Until then, you can use the one for Impressive Title, the game made by the same creators before they made FeralHeart:
http://fav.me/d5whgtmIt will help with downloads and basics of Blender, which is what is used for FeralHeart/Impressive Title.
Completely ignore sections III and V, since they pertain to Impressive Title and not FeralHeart.If you get that far, you're free to shoot me a message with any questions about how to further proceed with getting the item into FeralHeart.
Same goes for anyone else who may be reading.
