We're going to look at the process of setting up Product Category Banners like this
Once the demo data is imported, go to WordPress -> Products -> Categories and Edit any category.
Once you are on the Edit Category screen you should see something like this
Upload your chosen image - our recommended size is 825px * 206px to match our main demo.
Please also ensure you complete the Product Category Name and description to populate the rest of the banner content.
All done! Repeat the process for all categories.
