+## Getting Started
+3 minutes to run MNIST.
+1. Clone the demo code from OneFlow documentation
+```
+git clone https://github.com/Oneflow-Inc/oneflow-documentation.git
+cd oneflow-documentation/cn/docs/code/quick_start/ 
+```
+2. Run it in Python
+```
+python mlp_mnist.py
+```
+
+3. Oneflow is running and you got the training loss
