+
+## 简介
+
+PaddleNLP 2.0拥有丰富的模型库、简洁易用的API与高性能的分布式训练的能力，旨在为飞桨开发者提升文本建模效率，并提供基于PaddlePaddle 2.0的NLP领域最佳实践。
+
+## 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，更多详细介绍请查看[PaddleNLP模型库](./docs/model_zoo.md)。
+
+- **简洁易用的API**
+  - 深度兼容飞桨2.0的高层API体系，提供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量，提升文本建模开发效率。
+
+- **高性能分布式训练**
+  - 通过深度优化的混合精度训练策略与Fleet分布式训练API，可充分利用GPU集群资源，高效完成大规模预训练模型的分布式训练。
+
+
+## 安装
+
+### 环境依赖
+
+- python >= 3.6
+- paddlepaddle >= 2.0.0
+
+```
+pip install paddlenlp==2.0.0rc
+```
+
+## 快速开始
+
+### 数据集快速加载
+
+```python
+from paddlenlp.datasets import ChnSentiCorp
+
+train_ds, dev_ds, test_ds = ChnSentiCorp.get_datasets(['train', 'dev', 'test'])
+```
+
+可参考[Dataset文档](./docs/datasets.md)查看更多数据集。
+
+### 一键加载中文词向量
+
+```python
+from paddlenlp.embeddings import TokenEmbedding
+
+wordemb = TokenEmbedding("w2v.baidu_encyclopedia.target.word-word.dim300")
+print(wordemb.cosine_sim("国王", "王后"))
+>>> 0.63395125
+wordemb.cosine_sim("艺术", "火车")
+>>> 0.14792643
+```
+
+内置50+中文词向量，更多使用方法请参考 [Embedding文档](./examples/word_embedding/README.md)。
+
+
+### 一键加载高质量中文预训练模型
+
+```python
+from paddlenlp.transformers import ErnieModel, BertModel, RobertaModel, ElectraModel, GPT2ForPretraining
+
+ernie = ErnieModel.from_pretrained('ernie-1.0')
+bert = BertModel.from_pretrained('bert-wwm-chinese')
+roberta = RobertaModel.from_pretrained('roberta-wwm-ext')
+electra = ElectraModel.from_pretrained('chinese-electra-small')
+gpt2 = GPT2ForPretraining.from_pretrained('gpt2-base-cn')
+```
+
+请参考 [Pretrained-Models](./docs/transformers.md)查看目前支持的预训练模型。
+
