 ## Device Testing
 
+### Installation
+
+The Android build produces both an APK and an OBB file. **Both must be deployed for each build**:
+
 ```batch
-:: Install both apps
-adb install -r path\to\MosisService.apk
+:: Install APK
 adb install -r Binaries\Android\MosisUnreal-arm64.apk
 
+:: Create OBB directory and push OBB file
+adb shell mkdir -p /sdcard/Android/obb/com.omixlab.MosisUnreal
+adb push Binaries\Android\main.1.com.omixlab.MosisUnreal.obb /sdcard/Android/obb/com.omixlab.MosisUnreal/
+
+:: Install MosisService
+adb install -r path\to\MosisService.apk
+```
+
+Alternatively, use the generated install script:
+```batch
+cd Binaries\Android
+Install_MosisUnreal-arm64.bat
+```
+
+### Launching
+
+```batch
 :: Launch service first
 adb shell am start -n com.omixlab.mosis/.MainActivity

+
+## Meta Quest Configuration
+
+### Hand Tracking Support
+
+The plugin includes hand tracking support to allow launching on Quest devices without controllers. This is configured in `MosisSDK_UPL.xml`:
+
+```xml
+<uses-feature android:name="oculus.software.handtracking" android:required="false" />
+<uses-permission android:name="horizonos.permission.HAND_TRACKING" />
+```
+
+**Note**: Uses `horizonos.permission.HAND_TRACKING` (not the deprecated `com.oculus.permission.HAND_TRACKING`).
+
+### OculusXR Settings
+
+Hand tracking is also enabled in `DefaultEngine.ini`:
+
+```ini
+[/Script/OculusXRHMD.OculusXRHMDRuntimeSettings]
+bSupportHandTracking=True
+HandTrackingSupport=ControllersAndHands
+HandTrackingFrequency=High
+HandTrackingVersion=V2
 ```
