+Step-by-Step
+============
+
+This document list steps of reproducing Keras mnist model tuning results via Neural Compressor.
+This example can run on Intel CPUs.
+
+# Prerequisite
+
+### 1. Installation
+Recommend python 3.6 or higher version.
+
+```shell
+# Install Intel® Neural Compressor
+pip install neural-compressor
+```
+
+### 2. Install Tensorflow
+```shell
+pip install tensorflow
+```
+> Note: Supported Tensorflow version > 2.10.0.
+
+### 3. Installation Dependency packages
+```shell
+cd examples/keras/mnist/
+pip install -r requirements.txt
+```
+
+#### Quantizing the model on Intel CPU(Experimental)
+Intel Extension for Tensorflow for Intel CPUs is experimental currently. It's not mandatory for quantizing the model on Intel CPUs.
+
+```shell
+pip install --upgrade intel-extension-for-tensorflow[cpu]
+```
+
+# Run
+
+  ```shell
+  cd examples/keras/mnist/
+  python mnist.py
+  ```
