+### Adapt to PC Browsers
+
+Vant is a mobile-first component library, if you want to use Vant in PC browsers, you can use the [@vant/touch-emulator](https://github.com/youzan/vant/tree/dev/packages/vant-touch-emulator) module. This module will automatically convert the mouse events of the PC browser into the touch events of the mobile browser.
+
+```bash
+# Install
+npm i @vant/touch-emulator -S
+```
+
+```js
+// Just import this module, then Vant works in PC browser
+import '@vant/touch-emulator';
+```
