 ### 配置
 
-```javascript
-// .umirc.js
-export default {
-  mountElementId: false,
-  history: {
-    type: 'memory',
-  },
-};
-```
-
-**注意：RN 环境中没有 DOM 和 BOM， 所以这两项配置为必填，需要覆盖[umi](https://umijs.org/)的默认值，避免运行时进入到调用 DOM/BOM API 的代码分支导致运行错误。**
-
-- `mountElementId`：[umi](https://umijs.org/) 默认值是：`'root'`，在 RN 中**必须覆盖为`false`或空字符串**。
-- `history`：[umi](https://umijs.org/) 默认值是：`'browser'`，在 RN 中**只能使用：`'memory'`类型**。
+安装依赖后，开箱即用。零配置，直接使用缺省值即可。
