 - **Source**: The binary is compiled from [nitanmarcel/isodrive](https://github.com/nitanmarcel/isodrive)
 - **Why required**: Android apps cannot directly access USB gadget interfaces - they need a native binary with root privileges
-- **Location**: Place the compiled binary at `app/src/main/assets/bin/isodrive`
-- **Architecture**: Must be compiled for ARM64 (aarch64) for modern Android devices
+- **Location**: Place the binary at `app/src/main/assets/bin/isodrive`
+- **Supported architectures**: ARM64 (arm64-v8a), ARM32 (armeabi-v7a), x86, x86_64
 
 **How to obtain the binary:**
 
-Option 1: Download precompiled binary from [isodrive releases](https://github.com/nitanmarcel/isodrive/releases)
+1. Download the latest release from [isodrive-magisk releases](https://github.com/nitanmarcel/isodrive-magisk/releases/latest)
 
-Option 2: Compile from source:
-```bash
-# Clone isodrive repository
-git clone https://github.com/nitanmarcel/isodrive.git
-cd isodrive
+2. Extract the `isodrive-magisk-v<version>.zip` file
 
-# Build for Android (requires Android NDK)
-# Follow the build instructions in the isodrive repository
-```
+3. The binaries for each architecture are in the `libs/` directory:
+   ```
+   libs/
+   ├── arm64-v8a/
+   │   └── isodrive
+   ├── armeabi-v7a/
+   │   └── isodrive
+   ├── x86/
+   │   └── isodrive
+   └── x86_64/
+       └── isodrive
+   ```
+
+4. Copy the binary for your target architecture to `app/src/main/assets/bin/isodrive`
+   - For most modern devices: use `arm64-v8a/isodrive`
+   - The app can bundle multiple architectures if needed
