In some cases, you might need to add information that's not present in your import feed yet; for example, setting the "age_group" for your products (adults, kids etc.). To do that, you'll need to add a new field. You can add a new field by clicking the Setup Project Fields section, scroll to the bottom and click on '+ add project field'. A new screen will open up, and here you can insert the name of the field and the type of the field. It is recommended that you use a standard Channable field name, because this makes it easier to set up Channels later on.
