-## Building from Source
-
-### Prerequisites
-
-Before building the app, you need to obtain the `isodrive` binary:
-
-1. The `isodrive` binary is compiled from [nitanmarcel/isodrive](https://github.com/nitanmarcel/isodrive)
-2. Place the compiled binary at `app/src/main/assets/bin/isodrive` before building
-3. The binary must be executable and compiled for the appropriate Android architecture
-
-### Build Steps
-
-```bash
-# Clone the repository
-git clone https://github.com/yourusername/ISODroid.git
-cd ISODroid
-
-# Ensure isodrive binary is present
-ls -la app/src/main/assets/bin/isodrive
-
-# Build the APK
-./gradlew assembleRelease
-```
+> **Note**: The app includes a bundled `isodrive` binary. No additional setup required!

-## 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
