+# Module Overview
+
+A module is the smallest unit that implements basic functionality. Modules typically use a single model to accomplish specific tasks, such as text detection, image classification, and other basic functions. As fundamental building blocks, modules provide the necessary functional support for more complex application scenarios. This design approach allows users to flexibly select and combine different modules according to their needs, thereby simplifying the development process and enhancing development flexibility and efficiency.

+# 模块概述
+
+模块是实现基本功能的最小单位。模块通常使用单个模型去完成特定的任务，比如文本检测、图像分类等基本功能。模块作为基础构建单元，为更复杂的应用场景提供了必要的功能支持。这种设计方式使得用户可以根据需要灵活选择和组合不同的模块，从而简化了开发流程，并提高了开发的灵活性和效率。

+# Pipeline Overview
+
+A pipeline is a practical functional implementation composed of one or more modules. Through reasonable module combination and configuration, pipelines can meet the needs of complex application scenarios, such as technological applications like Optical Character Recognition (OCR). Pipelines not only demonstrate the integrated application of basic modules but also support capabilities such as high-performance inference and service-oriented deployment, providing users with higher development efficiency and broader application possibilities.
