 ## Prequisite
 
 - To run this sample, copy nnstreamer-api library file (nnstreamer-YYYY-MM-DD.aar) into 'libs' directory.
+- For image classification, user should turn on MXNet option.

 - [How to build NNStreamer for Android](https://github.com/nnstreamer/nnstreamer/tree/master/api/android)
 
 ## Introduction
 
-This is a simple example to show how to use NNStreamer APIs and Android Camera API to utilize the style transfer model.
+1. This is a simple example to show how to use NNStreamer APIs and Android Camera API to utilize the style transfer model. (tflite model)
 
 - The topmost view is the preview image of the camera.
 - The bottom view shows style transferred image of the camera input.
 - The applied style changes after several seconds.
 
+2. This is a simple example to show how to use NNStreamer APIs and Android Camera API to utilize the image classification model. (MXNet model)
+
+- The topmost view is the preview image of the camera.
+- The bottom view shows the camera input and its classification result on the screen together.
+- The applied classification results change directly as the camera screen changes.
