The section available by going to Settings =>General =>Manufacturers, will allow you to create entries for the various manufacturers of your products. The entries can be created to contain the Manufacturer's name, website address, and logo. You can also add redirect links, header data and SEO functions to the manufacturer listing.
As products are added to the store, you can assign them to their respective manufacturer entries which can be used to provide your shoppers with a "Shop by Brand" navigation element.
