 ### 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。
-* 更多地，tools/config.txt中的参数及解释如下。
+更多参数如下：

-* 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。
