+###  Global Configuration
+
+Global Configuration（NZ_MODAL_CONFIG）
+
+if your want to set global configuration, you can use the value of provide `NZ_MODAL_CONFIG` to accomplish it.
+(eg, add `{ provide: NZ_MODAL_CONFIG, useValue: { nzMask: false }}` to `providers` of your module, you can import `NZ_MODAL_CONFIG` from `ng-zorro-antd`)
+
+The weight of global configuration, component default value, component input value:
+
+component input value > global configuration > component default value
+
+supported global configuration item
+```ts
+{
+    provide: NZ_MODAL_CONFIG,
+    useValue: {
+        nzMask?: boolean; // Whether show mask or not.
+        nzMaskClosable?: boolean; // Whether to close the modal dialog when the mask (area outside the modal) is clicked
+    }
+}
+```
+> Note: global configuration does not have default value which component has it.
+
 #### ModalButtonOptions (used to customize the bottom button)
 
 An array of `ModalButtonOptions` type can be passed to `nzFooter` for custom bottom buttons.

+
+### 全局配置
+
+全局配置（NZ_MODAL_CONFIG）
+如果要进行全局默认配置，你可以设置提供商 `NZ_MODAL_CONFIG` 的值来实现。
+（如：在你的模块的`providers`中加入 `{ provide: NZ_MODAL_CONFIG, useValue: { nzMask: false }}`，`NZ_MODAL_CONFIG` 可以从 `ng-zorro-antd` 中导入）
+
+全局配置，组件默认值，组件层级配置之间的权重如下：
+
+组件层级配置 > 全局配置 > 组件默认值
+
+当前支持的全局配置
+```ts
+{
+    provide: NZ_MODAL_CONFIG,
+    useValue: {
+        nzMask?: boolean; // 是否展示遮罩
+        nzMaskClosable?: boolean; // 点击蒙层是否允许关闭
+    }
+}
+```
+注：全局配置并无默认值，因为nzMask和nzMaskClosable默认值存在于组件中
+
 #### ModalButtonOptions（用于自定义底部按钮）
 
 可将此类型数组传入 `nzFooter`，用于自定义底部按钮。
