+## 1 安装
+
+<a name="paddle安装"></a>
+### 1.1 paddle 安装
+```
+# cpu
+pip install paddlepaddle
+
+# gpu
+pip instll paddlepaddle-gpu
+```
+
+<a name="paddleocr_package_安装"></a>
+### 1.2 paddleocr package 安装
+
+
+pip 安装
+```
+pip install "paddleocr>=2.0.4" # 推荐使用2.0.4版本
+```
+本地构建并安装
+```
+python3 setup.py bdist_wheel
+pip3 install dist/paddleocr-x.x.x-py3-none-any.whl # x.x.x是paddleocr的版本号
+```
+
+<a name="快速使用"></a>
+## 2 快速使用
+
+<a name="命令行运行"></a>
+### 2.1 命令行运行
+
+查看帮助信息
+
+```
+paddleocr -h
+```
+
+* 整图预测（检测+识别）
+
+Paddleocr目前支持80个语种，可以通过修改--lang参数进行切换，具体支持的[语种](#语种缩写)可查看表格。
+
+``` bash
+
+paddleocr --image_dir doc/imgs/japan_2.jpg --lang=japan
+```
+![](https://raw.githubusercontent.com/PaddlePaddle/PaddleOCR/release/2.0/doc/imgs/japan_2.jpg)
+
+结果是一个list，每个item包含了文本框，文字和识别置信度
+```text
+[[[671.0, 60.0], [847.0, 63.0], [847.0, 104.0], [671.0, 102.0]], ('もちもち', 0.9993342)]
+[[[394.0, 82.0], [536.0, 77.0], [538.0, 127.0], [396.0, 132.0]], ('天然の', 0.9919842)]
+[[[880.0, 89.0], [1014.0, 93.0], [1013.0, 127.0], [879.0, 124.0]], ('とろっと', 0.9976762)]

+```
+
+* 识别预测

+```
+
+![](https://raw.githubusercontent.com/PaddlePaddle/PaddleOCR/release/2.0/doc/imgs_words/japan/1.jpg)
+
+结果是一个tuple，返回识别结果和识别置信度
+
+```text

+```
+
+* 检测预测
+
+```
+paddleocr --image_dir PaddleOCR/doc/imgs/11.jpg --rec false
+```
+
+结果是一个list，每个item只包含文本框
+
+```
+[[26.0, 457.0], [137.0, 457.0], [137.0, 477.0], [26.0, 477.0]]

+......
+```
+
+<a name="python_脚本运行"></a>
+### 2.2 python 脚本运行
+
+ppocr 也支持在python脚本中运行，便于嵌入到您自己的代码中：
+
+* 整图预测（检测+识别）
+
+```
+from paddleocr import PaddleOCR, draw_ocr
+
+# 同样也是通过修改 lang 参数切换语种
+ocr = PaddleOCR(lang="korean") # 首次执行会自动下载模型文件
+img_path = 'doc/imgs/korean_1.jpg '
+result = ocr.ocr(img_path)
+# 打印检测框和识别结果
+for line in result:
+    print(line)
+
+# 可视化
+from PIL import Image
+image = Image.open(img_path).convert('RGB')
+boxes = [line[0] for line in result]
+txts = [line[1][0] for line in result]
+scores = [line[1][1] for line in result]
+im_show = draw_ocr(image, boxes, txts, scores, font_path='/path/to/PaddleOCR/doc/korean.ttf')
+im_show = Image.fromarray(im_show)
+im_show.save('result.jpg')
+```
+
+结果可视化:
+![](https://raw.githubusercontent.com/PaddlePaddle/PaddleOCR/release/2.0/doc/imgs_results/korean.jpg)
+
+
+* 识别预测
+
+```
+from paddleocr import PaddleOCR
+ocr = PaddleOCR(lang="german")
+img_path = 'PaddleOCR/doc/imgs_words/german/1.jpg'
+result = ocr.ocr(img_path, det=False, cls=True)
+for line in result:
+    print(line)
+```
+
+![](https://raw.githubusercontent.com/PaddlePaddle/PaddleOCR/release/2.0/doc/imgs_words/german/1.jpg)
+
+结果是一个tuple，只包含识别结果和识别置信度
+
+```
+('leider auch jetzt', 0.97538936)
+```
+
+* 检测预测
+
+```python
+from paddleocr import PaddleOCR, draw_ocr
+ocr = PaddleOCR() # need to run only once to download and load model into memory
+img_path = 'PaddleOCR/doc/imgs_en/img_12.jpg'
+result = ocr.ocr(img_path, rec=False)
+for line in result:
+    print(line)
+
+# 显示结果
+from PIL import Image
+
+image = Image.open(img_path).convert('RGB')
+im_show = draw_ocr(image, result, txts=None, scores=None, font_path='/path/to/PaddleOCR/doc/fonts/simfang.ttf')
+im_show = Image.fromarray(im_show)
+im_show.save('result.jpg')
+```
+结果是一个list，每个item只包含文本框
+```bash
+[[26.0, 457.0], [137.0, 457.0], [137.0, 477.0], [26.0, 477.0]]
+[[25.0, 425.0], [372.0, 425.0], [372.0, 448.0], [25.0, 448.0]]
+[[128.0, 397.0], [273.0, 397.0], [273.0, 414.0], [128.0, 414.0]]

+```
+
+结果可视化 ：
+![](https://raw.githubusercontent.com/PaddlePaddle/PaddleOCR/release/2.0/doc/imgs_results/whl/12_det.jpg)
+
+ppocr 还支持方向分类， 更多使用方式请参考：[whl包使用说明](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.0/doc/doc_ch/whl.md)。
+
+<a name="自定义训练"></a>
+## 3 自定义训练
+
+ppocr 支持使用自己的数据进行自定义训练或finetune, 其中识别模型可以参考 [法语配置文件](../../configs/rec/multi_language/rec_french_lite_train.yml)
+修改训练数据路径、字典等参数。
+
+具体数据准备、训练过程可参考：[文本检测](../doc_ch/detection.md)、[文本识别](../doc_ch/recognition.md)，更多功能如预测部署、
+数据标注等功能可以阅读完整的[文档教程](../../README_ch.md)。
