The example used for this tutorial shows the creation of multiple dynamic attributes. The attributes created are all product level attributes and are associated with a product as a whole, instead of a specific variant (or SKU).
Steps are included to associate these dynamic attributes with an existing attribute group, or to create a new attribute group for them. The attribute group can then either be associated with an existing product type, or a new product type can be created for it. Steps are also included that describe how to set values for the new attributes for a product and then view the attributes on the web site.
