-In the project directory, you can run:
+✨ 特性
 
-### `npm start`
 
-Runs the app in the development mode.<br />
-Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
+- 📕 详细的文档与介绍
+- 🎨 使用富有特色的Neumorphism拟物化风格
+- 📦 开箱即用的高质量 React 组件
+- 🔥 使用 TypeScript 开发，提供完整的类型定义文件
 
-The page will reload if you make edits.<br />
-You will also see any lint errors in the console.
 
-### `npm test`
+<br/>
 
-Launches the test runner in the interactive watch mode.<br />
-See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+## 安装
+使用 npm 或 yarn 安装
 
-### `npm run build`
+```
+$ npm install bigbear-ui --save
+```
 
-Builds the app for production to the `build` folder.<br />
-It correctly bundles React in production mode and optimizes the build for the best performance.
+## 引入样式
 
-The build is minified and the filenames include the hashes.<br />
-Your app is ready to be deployed!
+```
+import 'bigbear-ui/dist/index.css';
+```
 
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+## 在线文档
 
-### `npm run eject`
+https://yehuozhili.github.io/bigbear-ui/
 
-**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
+<br/>
 
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
 
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
+## 本地文档
 
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
+下载代码，npm安装，使用`npm run storybook`即可获得本地文档。

-## Learn More
+## 制作初衷
 
-You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
+制作一个属于自己的组件库应该是每个前端人员都有的梦想，有时候自己写出某些好的组件也想记录下来。
