Yes, once Atlas generates the product page, you can edit it just like any other product in Shopify.
What you can edit:
Title, description, and images
Pricing and variants
Search engine listing (SEO)
Layout and content using the theme editor
To edit, go to Products > [Your Product] in Shopify, or use Online Store > Themes > Customize to change how it looks in your theme.
Tip: Atlas gives you a complete starting point, but you can change anything to match your brand or strategy.
