-## Introduction
 
-PaddleNLP aims to accelerate NLP applications through powerful model zoo, easy-to-use API with detailed tutorials, It's also the NLP best practice for PaddlePaddle 2.0 API system.
+# 特性
+
+- **丰富的模型库**
+
+  - 涵盖了NLP主流应用相关的前沿模型，包括中文词向量、预训练模型、词法分析、文本分类、文本匹配、文本生成、机器翻译、通用对话、问答系统等。
+
+- **简洁易用的API**
+
+  - 深度兼容飞桨2.0的高层API体系，提供更多可复用的文本建模模块，可大幅度减少数据处理、组网、训练环节的代码开发，提高开发效率。
 
-**This project is still UNDER ACTIVE DEVELOPMENT.**
+- **高性能分布式训练**
 
-## Features
+  - 通过高度优化的Transformer网络实现，结合混合精度与Fleet分布式训练API，可充分利用GPU集群资源，高效完成预训练模型的分布式训练。
 
-* **Rich and Powerful Model Zoo**
-  - Our Model Zoo covers mainstream NLP applications, including Lexical Analysis, Syntactic Parsing, Machine Translation, Text Classification, Text Generation, Text Matching, General Dialogue and Question Answering etc.
-* **Easy-to-use API**
-  - The API is fully integrated with PaddlePaddle high-level API system. It minimizes the number of user actions required for common use cases like data loading, text pre-processing, training and evaluation. which enables you to deal with text problems more productively.
-* **High Performance and Large-scale Training**
-  - We provide a highly optimized ditributed training implementation for BERT with Fleet API, it can fully utilize GPU clusters for large-scale model pre-training. Please refer to our [benchmark](./benchmark/bert) for more information.
-* **Detailed Tutorials and Industrial Practices**
-  - We offers detailed and interactable notebook tutorials to show you the best practices of PaddlePaddle 2.0.
