+## Toast 轻提示
+
+### 使用指南
+
+在 index.json 中引入组件
+```json
+"usingComponents": {
+  "van-toast": "path/to/vant-weapp/dist/toast/index"
+}
+```
+
+### 代码演示
+
+#### 文字提示
+
+```javascript
+const Toast = require('path/to/vant-weapp/dist/toast/index');

+```

+<van-toast id="van-toast" />
+```
+
+#### 加载提示
+
+```javascript
+Toast.loading({
+  mask: true,
+  message: '加载中...'
+});
+```
+
+
+#### 成功/失败提示
+
+```javascript
+Toast.success('成功文案');
+Toast.fail('失败文案');
+```
+
+
+#### 高级用法
+
+```javascript
+const toast = Toast.loading({
+  duration: 0,       // 持续展示 toast
+  forbidClick: true, // 禁用背景点击
+  message: '倒计时 3 秒',
+  loadingType: 'spinner',
+  selector: '#custom-selector'
+});
+
+let second = 3;
+const timer = setInterval(() => {
+  second--;
+  if (second) {
+    toast.setData({
+      message: `倒计时 ${second} 秒`
+    });
+  } else {
+    clearInterval(timer);
+    Toast.clear();
