+## Running on Intel GPU
+The sample code is CPU based, but you can run it using Intel(R) Extension for TensorFlow* with Intel(R) Data Center GPU Flex Series freely. 
+
+If you are using the Intel GPU, please refer to [Intel GPU Software Installation](https://intel.github.io/intel-extension-for-tensorflow/latest/docs/install/install_for_gpu.html)
+
+It should be able to run on Intel GPU seamlessly and without any code change.
