+
+## 微库提供的功能与说明
+
+stb库是一系列高效的C/C++库，由Sean T. Barrett开发，采用单文件设计，每个stb库都是一个单独的头文件，这使得集成变得非常简单。只需将头文件包含到你的项目中，无需额外的编译步骤或库文件。主要用于图形和音频处理。
+
+得益于其实现方式，当仅需要将图像数据载入内存、或进行缩放操作、或保存图像时使用stb会非常方便，因为仅需要include几个头文件即可，不需要额外图像处理库的依赖，如libjpeg、libpng、opencv等。
+
+stb支持的详细特性可见其官方文档： https://github.com/nothings/stb
+
+本仓库将stb作为微库移植到TenonOS，目录结构如下：
+
+```powershell
+.
+├── Config.uk   ------ 维护微库配置
+├── Makefile.uk ------ 用于微库构建
+└── patches     ------ 维护对stb源码的修改
+```
+
+## 编译构建与配置说明
+
+stb微库不依赖其他微库，默认不启用
