+### 介绍
+
+显示一个任务或流程的进度，常用于开通流程。
+
+### 安装
+
+```javascript
+import { Indicator } from '@nutui/nutui-react'
+```
+### 基础用法
+:::demo
+```tsx
+import  React from "react";
+import { Indicator, Cell, Button } from '@nutui/nutui-react';
+
+const App = () => {
+  return (
+    <Cell>
+      <Indicator size={3} current={3}>
+      </Indicator>
+    </Cell>
+    <Cell>
+      <Row>
+        <Col span="12">
+          <Button size="small" type="primary">
+            主要按钮
+          </Button>
+        </Col>
+        <Col span="12">
+          <Indicator block={true} align="right" size={6} current={5}>
+          </Indicator>
+        </Col>
+      </Row>
+    </Cell>
+  );
+};
+export default App;
+```
+:::
+### block用法
+在`block`为true时，将表现为块级元素，可通过`align`，设置对齐方式
+:::demo
+```tsx
+import  React from "react";
+import { Indicator, Cell } from '@nutui/nutui-react';
+
+const App = () => {
+  return (
+    <Cell>
+      <Indicator block={true} align="center" size={6} current={5}>
+      </Indicator>
+    </Cell>
+    <Cell>
+      <Indicator block={true} align="left" size={6} current={1}>
+      </Indicator>

+      <Indicator block={true} align="right" size={6} current={5}>
+      </Indicator>
+    </Cell>
+  );

+### 不补0
