+#### Quest Deployment
+
+**IMPORTANT**: Git Bash on Windows converts Unix paths to Windows paths. Use `MSYS_NO_PATHCONV=1` prefix for all adb push commands.
+
+```bash
+# Set Quest device ID (check with: adb devices -l)
+QUEST=2G0YC5ZF7W01T0
+
+# Install APK
+adb -s $QUEST install -r D:/Dev/Mosis/MosisUnreal/Binaries/Android/MosisUnreal-arm64.apk
+
+# Create OBB temp directory
+adb -s $QUEST shell "mkdir -p /data/local/tmp/obb/com.omixlab.MosisUnreal"
+
+# Push OBB to temp location (MUST use MSYS_NO_PATHCONV=1)
+MSYS_NO_PATHCONV=1 adb -s $QUEST push D:/Dev/Mosis/MosisUnreal/Binaries/Android/main.1.com.omixlab.MosisUnreal.obb /data/local/tmp/obb/com.omixlab.MosisUnreal/
+
+# Move OBB to final location
+adb -s $QUEST shell "rm -rf /sdcard/Android/obb/com.omixlab.MosisUnreal"
+adb -s $QUEST shell "mv /data/local/tmp/obb/com.omixlab.MosisUnreal /sdcard/Android/obb/"
+
+# Start MosisService first, then MosisUnreal
+adb -s $QUEST shell am start -n com.omixlab.mosis/.MainActivity
+sleep 3
+adb -s $QUEST shell am start -n com.omixlab.MosisUnreal/com.epicgames.unreal.GameActivity
+
+# Monitor logs

+```
+
+**Common issues**:
+- App stuck on loading screen: OBB not pushed or wrong version
+- `adb push` path errors: Missing `MSYS_NO_PATHCONV=1` prefix
+- Service not connecting: Start `com.omixlab.mosis` before the game
