+#### Preferable Inference Mode
+
+If you've built native libraries for CPU (i.e. `--desktop cpu`), select `CPU` for inference mode.\
+When building for Android/iOS, make sure that you select `GPU` for inference mode, because `CPU` inference mode is not supported currently.

+#### Asset Loader Type
+
+The default Asset Loader Type is set to `Local`, which only works on UnityEditor.\
