+## About ant-design-vue
+
+As we all know, Ant Design, as a design language, has gone through many years of iteration and accumulation. Its UI design ideas have become a set of de facto standards and are sought after and loved by many front-end developers and enterprises, and it is also a magic weapon in the hands of React developers. I hope that ant-design-vue will allow Vue developers to enjoy the excellent design of Ant Design.
+
+The ant-design-vue is the Vue implementation of Ant Design. The style of the component is kept in sync with Ant Design. The html structure and css style of the component are also consistent. The style 0 modification is really achieved, and the component API is kept as consistent as possible.
+
+Ant Design Vue is committed to providing programmers with a ** pleasant ** development experience.
