+## 关于桌面端组件
+
+Vant Cli 也支持预览桌面端组件，你可以在组件的 `demo` 目录下新建一个 `.vue` 文件，并在组件的 `README` 中按如下格式声明要预览的组件：
+
+```html
+<demo-code>./demo/MyDemo.vue</demo-code>
+```
+
+`demo-code` 标签中间的文本为 `README` 到 `demo` 文件的相对路径。
+
+```
+button
+├─ demo             # 组件示例
+│   └─ MyDemo.vue   # 要预览的 demo 文件
+├─ index.js         # 组件入口
+├─ index.less       # 组件样式
+└─ README.md        # 组件文档
+```

+
+`demo-code` 标签支持以下属性：
+
+| 名称      | 类型    | 描述                                    |

+
+### 去除手机模拟器
+
+对于 PC 端的组件，如果不需要右侧的手机模拟器，可以在 `vant.config.js` 文件中设置 `site.hideSimulator` 为 `true`，这样在所有页面都会隐藏手机模拟器，也可以只针对具体页面设置。
+
+```js
+module.exports = {
+  site: {
+    defaultLang: 'zh-CN',
+    hideSimulator: true, // 所有页面都不显示
+    locales: {
+      'zh-CN': {
+        title: 'Vant',
+        description: '轻量、可靠的移动端 Vue 组件库',
+        hideSimulator: true, // 中文下所有页面都不显示
+        nav: [
+          {
+            title: '基础组件',
+            items: [
+              {
+                path: 'button',
+                title: 'Button 按钮',
+                hideSimulator: true, // 只针对某个页面不显示
