-## Motivation
 Paddle Serving helps deep learning developers deploy an online inference service without much effort. **The goal of this project**: once you have trained a deep neural nets with [Paddle](https://github.com/PaddlePaddle/Paddle), you already have a model inference service. A demo of serving is as follows:

-## Key Features
+<h2 align="center">Key Features</h2>
+
 - Integrate with Paddle training pipeline seemlessly, most paddle models can be deployed **with one line command**.
 - **Industrial serving features** supported, such as models management, online loading, online A/B testing etc.
 - **Distributed Key-Value indexing** supported that is especially useful for large scale sparse features as model inputs.

 - **Multiple programming languages** supported on client side, such as Golang, C++ and python
 - **Extensible framework design** that can support model serving beyond Paddle.
