+## Stepper 计数器
+
+### 使用指南
+在 app.wxss 中引入组件库所有样式
+```css
+@import "path/to/zanui-weapp/dist/index.wxss";
+```
+
+在需要使用的页面里引入组件库模板和脚本
+```html
+<import src="path/to/zanui-weapp/dist/stepper/index.wxml" />
+
+<template is="zan-stepper" data="{{ ...stepper, componentId: 'stepper' }}"></template>
+```
+```js
+const Stepper = require('path/to/zanui-weapp/dist/stepper/index');
+
+// 在 Page 中混入 Stepper 里面声明的方法
+Page(Object.assign({}, Stepper, {
+  // ...
+}));
+```
+
+### 代码演示
+#### 基础功能
+`Stepper` 组件通过传入的 stepper 对象控制，内部数据格式如下：
+```js
+const stepper = {
+  // 当前 stepper 数字
+  stepper: 1,
+  // 最小可到的数字
+  min: 1,
+  // 最大可到的数字
+  max: 1
+};
+```
+
+当一个 `Stepper` 中，min 超过 max，就会导致组件被置灰
+
+当 stepper 被点击时，可以在页面中注册 handleZanStepperChange 方法来监听
+```js
+Page(Object.assign({}, Stepper, {
+  handleZanStepperChange({ componentId, stepper }) {
+    // componentId 即为在模板中传入的 componentId
+    // 用于在一个页面上使用多个 stepper 时，进行区分
+    // stepper 代表操作后，应该要展示的数字，需要设置到数据对象里，才会更新页面展示
+    this.setData({
+      stepper
+    });
+  }
+}));
+```
