+# Use Tensorflow Lite in SGX with Occlum
+
+Step 1: Download Tensorflow, build Tensorflow Lite, and download models
+```
+./download_and_build_tflite.sh
+```
+When completed, the resulting Tensorflow can be found in `tensorflow_src` directory, the Tensorflow Lite Model can be found in `models` directory
+
+Step 2.1: To run TensorFlow Lite inference demo in Occlum, run
+```
+./run_tflite_in_occlum.sh demo
+```
+
+Step 2.2: To run TensorFlow Lite inference benchmark in Occlum, run
+```
+./run_tflite_in_occlum.sh benchmark
+```
+
+Step 3.1: To run TensorFlow Lite inference demo in Linux, run
+```
+./run_tflite_in_linux.sh demo
+```
+
+Step 3.2: To run TensorFlow Lite inference benchmark in Linux, run
+```
+./run_tflite_in_linux.sh benchmark
