 If a build is taking too long or going in the wrong direction, you can cancel it and try a different prompt.
 
+### Restoring an earlier version
+
+If a recent prompt took the app in the wrong direction, you can roll back to any earlier ready version and keep iterating from there.
+
+1. Click an earlier version in the version timeline to preview it.
+2. In the callout above the preview, click **Restore this version**.
+3. Confirm in the dialog.
+
+Restoring duplicates the selected version to the head of the timeline as a new latest version. Your next prompt iterates from the restored version, while the intermediate versions stay in the timeline as history. The restore happens instantly — there's no rebuild.

 ### Query inspector
 
 When an app runs a query, it will appear in the query inspector. Open it to see every query the running app is making - the underlying metric query, the fields it's pulling, and the results it gets back. Use it to verify the app is asking for the right data, debug unexpected numbers, or sanity-check performance.
