Why -- Product Display Type needed after Product Type created?
I am trying to understand the connections between the
Product = I create this first
Product Type = I create this second
Product Display, which is content type. = I create this third.
I create a new product
I create product... Apples, and include photo, etc.
Then I create Product Type with manage fields and then Display fields for the product type FRUIT.
Then I create Product Display (content type) DISPLAY FRUITS. I would just like to find a careful explanation of how these 3 are related and what is important about each in building a store.
After I create the Product Type, then I create Product Display, which appears to me just a mirror of Product Type?
The kickstart is working fine, but I would like to read or view a very clear explanation of why the above procedure.
I'd appreciate a link or something that explains very carefully.
