Ant Design React is dedicated to providing a **good development experience** for programmers. Make sure that you had installed [Node.js](https://nodejs.org/)(> v6.5) correctly.
> Before delving into Ant Design React, a good knowledge base of [React](http://facebook.github.io/react/) and [JavaScript ES2015](http://babeljs.io/docs/learn-es2015/) is needed.
The following CodeSandbox demo is the simplest use case, and it's also a good habit to fork this demo to provide a re-producible demo while reporting a bug.
During development, you may need to compile and debug JSX and ES2015 code, and even proxy some of the requests to mock data or other external services. All of these can be done with quick feedback provided through hot reloading of changes.
[antd-init](https://github.com/ant-design/antd-init/) is a demo-only scaffold tool. If you want to create real world projects, [dva-cli](https://github.com/dvajs/dva-cli) and [create-react-app](https://github.com/facebookincubator/create-react-app) is our recommendation.
Read [the documentation of `antd-init`](https://github.com/ant-design/antd-init/) and [the documentation of `ant-tool`](http://ant-tool.github.io/) to explore more features.
You need to provide [es5-shim](https://github.com/es-shims/es5-shim) and [es6-shim](https://github.com/paulmillr/es6-shim) and other polyfills for IE browsers.
If you are using babel, we strongly recommend using [babel-polyfill](https://babeljs.io/docs/usage/polyfill/) and [babel-plugin-transform-runtime](https://babeljs.io/docs/plugins/transform-runtime/) instead of those two shims.
> If you run into problems with [startsWith ](https://github.com/ant-design/ant-design/issues/3400#issuecomment-253181445), you should import [es6-shim](https://github.com/paulmillr/es6-shim) or [babel-polyfill](https://babeljs.io/docs/usage/polyfill/) as a workaround.
You may encounter problems like [#28](https://github.com/ant-tool/atool-build/issues/28) and [#858](https://github.com/ant-design/ant-design/issues/858), since `babel@6.x` doesn't support IE8. You can refer to this [webpack config](https://github.com/ant-design/antd-init/blob/f5fb9479ca973fade51fd6754e50f8b3fafbb1df/boilerplate/webpack.config.js#L4-L8).
Also, you can use any [scaffold](https://github.com/enaqx/awesome-react#boilerplates) available in the React ecosystem. If you encounter problems, you can use our [webpack config](https://github.com/ant-tool/atool-build/blob/master/src/getWebpackCommonConfig.js) and [modify it](http://ant-tool.github.io/webpack-config.html).
If you are trying [parcel](https://parceljs.org), here is [a demo repository](https://github.com/ant-design/parcel-antd).
There are some [scaffolds](http://scaffold.ant.design/) which have already integrated antd, so you can try and start with one of these, and even contribute.
If you see logs like below screenshot, you might be importing all components by writing `import { Button } from 'antd';`. This will affect your app's network performance.
We strongly recommend using [babel-plugin-import](https://github.com/ant-design/babel-plugin-import), which can convert the following code to the 'antd/lib/xxx' way:
> FYI, babel-plugin-import's `style` option will importing some global reset styles, don't use it if you don't need those styles. You can import styles manually via `import 'antd/dist/antd.css'` and override the global reset styles.
