+## Technical Details
+
+ISO Droid uses the `isodrive` binary to interface with the Linux USB gadget subsystem. The app:
+- Bundles the isodrive binary in `app/src/main/assets/bin/`
+- Extracts and executes it with root permissions at runtime
+- Supports both configfs (modern) and sysfs (legacy) USB gadget modes
+- Dynamically detects available OS icons for file display
