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 going to the Project Fields tab, then clicking 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.
