-## How to contribute
 
+#### 1. Use [babel-plugin-import](https://github.com/ant-design/babel-plugin-import) (Recommended)
+```bash
+# Install babel-plugin-import
+npm i babel-plugin-import -D
+```
+
+```js
+// set babel config in .babelrc or babel-loader
+{
+  "plugins": [
+    ["import", { "libraryName": "vant", "style": true }]
+  ]
+}
+```
+
+Then you can import components from vant, equivalent to import manually below.
+
+```js
+import { Button } from 'vant';
+```
+
+#### 2. Manually import
+
+```js
+import { Button } from 'vant/lib/button';
+import 'vant/lib/vant-css/base.css';
+import 'vant/lib/vant-css/button.css';
+```
+ 
+#### 3. Import all components
+
+```js
+import Vue from 'vue';
+import Vant from 'vant';
+import 'vant/lib/vant-css/index.css';
+
+Vue.use(Vant);
+```
