+
+### Intro
+
+The default language of Vant is Chinese. If you want to use other languages, you can follow the instructions below.
+
+### Switch languages
+
+Vant supports multiple languages with the Locale component, and the `Locale.use` method allows you to switch to different languages.
+
+```js
+import { Locale } from 'vant';
+import enUS from 'vant/lib/locale/lang/en-US';
+
+Locale.use('en-US', enUS);
+```
+
+### Modify default configs
+
+Use `Locale.add` method to modify the default configs.
+
+```js
+import { Locale } from 'vant';
+
+const messages = {
+  'en-US': {
+    vanPicker: {
+      confirm: 'Close',
+    },
+  },
+};
+
+Locale.add(messages);
+```
