 Install PaddlePaddle refer to [Installation Guide](https://www.paddlepaddle.org.cn/en/install/quick?docurl=/documentation/docs/en/develop/install/pip/linux-pip_en.html), after then, install the PaddleOCR toolkit.
 
 ```bash
-# Install paddleocr
-pip install paddleocr
+# If you only want to use the basic text recognition feature (returns text position coordinates and content), including the PP-OCR series
+python -m pip install paddleocr
+# If you want to use all features such as document parsing, document understanding, document translation, key information extraction, etc.
+# python -m pip install "paddleocr[all]"
 ```
 
+Starting from version 3.2.0, in addition to the `all` dependency group demonstrated above, PaddleOCR also supports installing partial optional features by specifying other dependency groups. All dependency groups provided by PaddleOCR are as follows:
+
+| Dependency Group Name | Corresponding Functionality |
+| - | - |
+| `doc-parser` | Document parsing: can be used to extract layout elements such as tables, formulas, stamps, images, etc. from documents; includes models like PP-StructureV3 |
+| `ie` | Information extraction: can be used to extract key information from documents, such as names, dates, addresses, amounts, etc.; includes models like PP-ChatOCRv4 |
+| `trans` | Document translation: can be used to translate documents from one language to another; includes models like PP-DocTranslation |
+| `all` | Complete functionality |

 In addition to the `all` dependency group demonstrated above, PaddleOCR also supports installing specific optional features by specifying other dependency groups. The available dependency groups provided by PaddleOCR are as follows:
 
-| Dependency Group | Functionality            |
-| ---------------- | ------------------------ |
-| `doc-parser`     | Document parsing, which can be used to extract layout elements in a document such as tables, formulas, stamps, and images. |

 The general OCR pipeline (e.g., PP-OCRv3/v4/v5) and the document image preprocessing pipeline can be used without installing any additional dependency groups. Apart from these two pipelines, each remaining pipeline belongs to one and only one dependency group. You can refer to the usage documentation of each pipeline to determine which group it belongs to. For individual functional modules, installing any dependency group that includes the module will enable access to its core functionality.

 通用 OCR 产线（如 PP-OCRv3/v4/v5）、文档图像预处理产线的功能无需安装额外的依赖组即可使用。除了这两条产线外，每一条产线属于且仅属于一个依赖组。在各产线的使用文档中可以了解产线属于哪一依赖组。对于单功能模块，安装任意包含该模块的产线对应的依赖组后即可使用相关的基础功能。
