Adding a product in Prestashop is actually a very easy thing to do.  However, if you start looking at all of the items that can be configured with it, then you may it find it a little challenging.  Products are the heart and soul of your shop and therefore may have information including pricing, associations, images, shipping, combinations, features, customization, attachments and stock information.  As you can see, what may have been the simple matter of one item quickly involves many other factors that are important for the management of your store.  The following tutorial gives you a quick overview of simply adding a product within Prestashop 1.5 while only generally discussing all of the detail of the other items/options involved with adding a product.
