+### 1. Environment Preparation
-PaddleOCR models has been built in PPOCRLabel, please refer to [PaddleOCR installation document](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/doc/doc_ch/installation.md) to prepare PaddleOCR and make sure it works.
+#### **Install PaddlePaddle 2.0**
+```bash
+pip3 install --upgrade pip
+# If you have cuda9 or cuda10 installed on your machine, please run the following command to install
+python3 -m pip install paddlepaddle-gpu==2.0.0 -i https://mirror.baidu.com/pypi/simple

 ## 安装
-### 1. 安装PaddleOCR
+### 1. 环境搭建
-PPOCRLabel内置PaddleOCR模型，故请参考[PaddleOCR安装文档](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/doc/doc_ch/installation.md)准备好PaddleOCR，并确保PaddleOCR安装成功。
+#### 安装PaddlePaddle
+```bash
+pip3 install --upgrade pip
+如果您的机器安装的是CUDA9或CUDA10，请运行以下命令安装
+python3 -m pip install paddlepaddle-gpu==2.0.0 -i https://mirror.baidu.com/pypi/simple
+如果您的机器是CPU，请运行以下命令安装
+python3 -m pip install paddlepaddle==2.0.0 -i https://mirror.baidu.com/pypi/simple
+```
+更多的版本需求，请参照[安装文档](https://www.paddlepaddle.org.cn/install/quick)中的说明进行操作。
+#### **安装PaddleOCR**
+```bash
+【推荐】git clone https://github.com/PaddlePaddle/PaddleOCR
+如果因为网络问题无法pull成功，也可选择使用码云上的托管：
+git clone https://gitee.com/paddlepaddle/PaddleOCR
+注：码云托管代码可能无法实时同步本github项目更新，存在3~5天延时，请优先使用推荐方式。
+```
+#### 安装第三方库
+```bash
+cd PaddleOCR
+pip3 install -r requirements.txt
+```
+注意，windows环境下，建议从[这里](https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely)下载shapely安装包完成安装， 直接通过pip安装的shapely库可能出现`[winRrror 126] 找不到指定模块的问题`。

 ### 运行demo
-* 执行以下命令，完成对一幅图像的OCR识别与检测。
+运行方式：  
+```shell
+./build/ppocr <mode> [--param1] [--param2] [...]
+```  
+其中，`mode`为必选参数，表示选择的功能，取值范围['det', 'rec', 'system']，分别表示调用检测、识别、检测识别串联（包括方向分类器）。具体命令如下：
+##### 1. 只调用检测：
+```shell
+./build/ppocr det \
+    --det_model_dir=inference/ch_ppocr_mobile_v2.0_det_infer \
+    --image_dir=../../doc/imgs/12.jpg
+```
+##### 2. 只调用识别：
+```shell
+./build/ppocr rec \
+    --rec_model_dir=inference/ch_ppocr_mobile_v2.0_rec_infer \
+    --image_dir=../../doc/imgs_words/ch/
+```
+##### 3. 调用串联：
 ```shell
-sh tools/run.sh
+# 不使用方向分类器
+./build/ppocr system \
+    --det_model_dir=inference/ch_ppocr_mobile_v2.0_det_infer \
+    --rec_model_dir=inference/ch_ppocr_mobile_v2.0_rec_infer \
+    --image_dir=../../doc/imgs/12.jpg
+# 使用方向分类器
+./build/ppocr system \
+    --det_model_dir=inference/ch_ppocr_mobile_v2.0_det_infer \
+    --use_angle_cls=true \
+    --cls_model_dir=inference/ch_ppocr_mobile_v2.0_cls_infer \
+    --rec_model_dir=inference/ch_ppocr_mobile_v2.0_rec_infer \
+    --image_dir=../../doc/imgs/12.jpg
 ```
-* 若需要使用方向分类器，则需要将`tools/config.txt`中的`use_angle_cls`参数修改为1，表示开启方向分类器的预测。

-* PaddleOCR也支持多语言的预测，更多支持的语言和模型可以参考[识别文档](../../doc/doc_ch/recognition.md)中的多语言字典与模型部分，如果希望进行多语言预测，只需将修改`tools/config.txt`中的`char_list_file`（字典文件路径）以及`rec_model_dir`（inference模型路径）字段即可。
