 ## Waterfall 瀑布流
 
-### 基础用法
+#### 全局注册
+
+`Waterfall`引入后就自动全局安装。如果需要，可以再次手动安装：
+
+```js
+import Vue from 'vue';
+import { Waterfall } from '@youzan/zanui-vue';
+
+Waterfall.install(Vue);
+```
+
+#### 局部注册
+
+如果你只是想在某个组件中使用`Waterfall`，你可以在对应组件中注册`Waterfall`指令，这样只能在你注册的组件中使用`Waterfall`：
+
+```js
+import { Waterfall } from '@youzan/zanui-vue';
+
+export default {
+  directives: {
+    WaterfallLower: Waterfall('lower'),
+    WaterfallUpper: Waterfall('upper')
+  }
+};
+```
