- Shopify theme developers and agencies
- Worth noticing
- The page distinguishes free theme-zip export from Pro changed-file export with a diff and MERGE-REPORT.md; in-app theme writing awaits Shopify review.
Field notes
The workflow depends on keeping a snapshot of the live theme from the moment its copy was made; that baseline lets the app attribute later changes to the live or working version. The page says conflicts can be resolved by selecting a side for a whole file or editing the merged result. For shipping, it describes a full-theme download or a changed-file push through Shopify CLI; writing into a theme from inside the app is still awaiting Shopify review.
