+        body: |
+          Changes were detected between your live store's Theme Configuration and config.json.
+
+          These may have been due to changes made in Page Builder, or because a theme was uploaded to your store out of sync with your source control.
+
+          By merging this PR, you can bring your local config.json in sync with the live store, and prevent issues where deploying your theme would overwrite recent changes.
+
+          Note that this is checked every few hours, so it's possible changes made very recently are not accounted for. You may re-run this action again manually to make sure everything is up to date.
