 # MuffinStore Jailed
 
-Hacked together on-device App Store client.
+Hacked together on-device App Store client, view it more-so as a PoC than as a final tool.
+
+The UI is a bit scuffed, there's no progress bar during downgrading so just wait on the screen until you get a popup that requests installation ( the time this takes depends on how big the app is, so please wait. ), and then after you press install wait like ~5 more seconds and then you can return to SpringBoard to see the app downgrade being finalized.
 
 I am not responsible for any issues caused by the usage of this tool, it's experimental and I will not be held accountable if anything happens. Use at your own risk. Although nothing should happen, just putting this here just in case.
