 # kivyblocks简介
 
+kivyblocks是一个基于kivy的python GUI开发工具，得益于kivy的跨平台特性， kivyblocks可以支持Windows，Linux，macosx， iPhone，android， 以及X霉
+
+
+## kivyblocks的目标
+降低前端原生应用开发的复杂度，提高原生应用系统的开发和运维效率。
+
+## kivyblocks的原理
+逻辑 + 数据 = 程序
+
+相信程序员都了解上述等式，kviyblocks将复杂的业务逻辑封装在底层的构件库中，而将标准的数据接口提供给程序员，程序员不需要编写逻辑代码
+
+程序要要创建一个显示构件，只需要按照[构件数据格式](./cdf.md)的要求填写字典数据即可
