What does 'Sort Order' mean

Sort order is a number used to allow you to put an item in a specific order. By default, your products will be ordered in the same order they are added to your account. If you'd like them ordered differently however, you can use the sort order to change the order. The product with the smallest sort order will be displayed first. For example, Product A with a sort order of 1 will be displayed before Product B with a sort order of 2.
