⚠️ As of February 25, 2026, Atlas no longer generates or imports themes. If you already have the Atlas theme installed, your theme is unaffected and everything in this article still applies. New users can use Atlas to generate home pages and product pages and import them into any Shopify theme. For the full breakdown, see What's new with Atlas: page builder update.
From your Shopify admin, go to Online Store > Themes
In your Theme Library, locate the Atlas Theme
Select Publish
Confirm when prompted — this will replace your current live theme
Once published, the Atlas Theme will be active on your storefront.
Tip: You can always switch back to a previous theme using the same method.
