 ## Instructions
 
-1. Get mBank's `base.apk` from your device - it usually sits somewhere in `/data/app/*/base.apk`
-2. Run the script with the APK as a parameter, and your real name as the second one - `./mbankDeadnameRemover.sh base.apk Laura`
+1. Download mBank's app from apps.evozi.com or other apk downloader. You can also use Aurora store for this; Do not steal the app from `/data/app/pl.mbank*/`, as this has produced corrupted and uninstallable files.
+2. Run the script with the APK as a parameter, and your real name as the second one - i.e. `./mbankDeadnameRemover.sh base.apk Laura`
 3. Transfer the patched APK back to your device
 4. Uninstall the old application from your device - this is needed, as Android won't let you install a self-signed application over another application
 5. Install the APK, pair the app with mBank
