+## 兼容其他 i18n 插件
+如果不使用 `vue-i18n`，而是用其他的 i18n 插件，Element 将无法兼容，但是可以自定义 Element 的 i18n 的处理方法。
+
+```javascript
+import Vue from 'vue'
+import Element from 'element-ui'
+import enLocale from 'element-ui/lib/locale/lang/en'
+import zhLocale from 'element-ui/lib/locale/lang/zh-CN'
+
+Vue.use(Element, {
+  i18n: function (path, options) {
+    // ...
+  }
+})
+```
+
 目前 Element 内置了以下语言：
 <ul class="language-list">
   <li>简体中文（zh-CN）</li>
