+## Circle 环形进度条
+
+### 使用指南
+``` javascript
+import { Circle } from 'vant';
+
+Vue.use(Circle);
+```
+
+### 代码演示
+
+#### 基础用法
+通过 `rate` 指定目标进度，`v-model` 代表当前进度，`speed` 控制动画速度
+
+```html
+<van-circle
+  v-model="currentRate"
+  :rate="30"
+  :speed="100"
+  :text="text"
+/>
+```
+
+``` javascript
+export default {
+  data() {
+    return {
+      currentRate: 0
+    };
+  },
+  computed: {
+    text() {
+      return this.currentRate.toFixed(0) + '%'
+    }
+  }
+};
+```
+
+#### 样式定制
+
+```html
+<van-circle
+  v-model="currentRate"
+  color="#13ce66"
+  fill="#fff"
+  size="120px"
+  layer-color="#eee"
