+When you set `manifestPlaceholders = true`, Gropify will automatically synchronize these properties' key-values to `manifestPlaceholders` in the android configuration method block.
+
+You can then use these placeholders directly in `AndroidManifest.xml`.
+
+> The following example
+
+```xml
+<manifest xmlns:android="http://schemas.android.com/apk/res/android">
+
+    <application
+        android:label="${project.appName}"
+        android:icon="@mipmap/ic_launcher">
+
+        ...
+    </application>
+</manifest>
+```
+
 You no longer need to use `buildConfigField` to add code to `BuildConfig`. With the property key-value code generated by `Gropify`, you can manage your project more flexibly.
 
 You can also use interpolation `${...}` in property key-values to reference each other's content, but recursive references are not allowed.

 你可以无需再使用 `buildConfigField` 向 `BuildConfig` 添加代码，有了 `Gropify` 生成的属性键值代码，你可以更加灵活地管理你的项目。
 
 你还可以在属性键值中使用插值 `${...}` 互相引用其中的内容，但不允许递归引用。
