 - 2021.4.9 支持**80种**语言的检测和识别
 - 2021.4.9 支持**轻量高精度**英文模型检测识别
 
+PaddleOCR 旨在打造一套丰富、领先、且实用的OCR工具库，不仅提供了通用场景下的中英文模型，也提供了专门在英文场景下训练的模型，
+和覆盖[80个语言](#语种缩写)的小语种模型。
+
+其中英文模型支持，大小写字母和常见标点的检测识别，并优化了空格字符的识别：

 -2021.4.9 supports the detection and recognition of 80 languages
 -2021.4.9 supports **lightweight high-precision** English model detection and recognition
 
+PaddleOCR aims to create a rich, leading, and practical OCR tool library, which not only provides
+Chinese and English models in general scenarios, but also provides models specifically trained
+in English scenarios. And multilingual models covering [80 languages](#language_abbreviations).
+
+Among them, the English model supports the detection and recognition of uppercase and lowercase
+letters and common punctuation, and the recognition of space characters is optimized:
