+# ButtonGroup 按钮组组件
+
+`ButtonGroup` 是一个用于聚合多个 `MaterialButton` 的容器组件。它支持灵活的布局切换、统一的属性默认值配置以及全局事件委托监听。
+
+## 核心特性
+
+- **布局自适应**：支持水平（Horizontal）和垂直（Vertical）两种排列方式。
+- **属性继承与覆盖**：可以在组级别设置默认的尺寸、颜色、图标等，也可以在具体的按钮项中进行个性化覆盖。
+- **智能类型识别**：内置了对 `download` 和 `normal` 类型的样式及图标自动匹配逻辑。
+- **事件委托**：支持统一监听 `@click` 事件，便捷获取点击的项信息及索引。
+
+## 组件属性 (Props)
+
+| 属性名 | 类型 | 默认值 | 可选值 | 说明 |
+| :--- | :--- | :--- | :--- | :--- |
+| `links` | `ExternalLink[]` | `[]` | - | 按钮配置数组 |
+| `layout` | `string` | `"horizontal"` | `"horizontal"`, `"vertical"` | 布局方向 |
+| `size` | `string` | `"s"` | `"xs"`, `"s"`, `"m"`, `"l"`, `"xl"` | 默认按钮尺寸 |
+| `color` | `string` | - | - | 默认按钮颜色样式 |
+| `icon` | `string` | - | - | 默认按钮图标 |
+| `target` | `string` | - | - | 默认链接打开方式 |
+| `ariaLabel` | `string` | - | - | 组的无障碍标签 |
+
+## 组件事件 (Emits)
+
+| 事件名 | 回调参数 | 说明 |
+| :--- | :--- | :--- |
+| `@click` | `(event: Event, item: ExternalLink, index: number)` | 当组内任意按钮被点击时触发 |
+
+## 按钮配置项 (ExternalLink)
+
+每一项 `links` 中的对象支持以下配置：
+
+| 属性名 | 类型 | 说明 |
+| :--- | :--- | :--- |
+| `label` | `string` | 按钮显示的文本内容 |
+| `id` | `string` | (可选) 自定义标识符，方便在事件处理中识别 |
+| `link` | `string` | (可选) 点击跳转的链接地址 |
+| `type` | `string` | (可选) 预设类型：`download` (充满色), `normal` (色调色) |
+| `icon` | `string` | (可选) 覆盖组设置的图标 |
+| `color` | `string` | (可选) 覆盖组设置的颜色 |
+| `size` | `string` | (可选) 覆盖组设置的尺寸 |
+| `target` | `string` | (可选) 覆盖组设置的打开方式 |
+| `ariaLabel` | `string` | (可选) 按钮的无障碍标签 |
+| `onClick` | `Function` | (可选) 单体独立的点击回调函数 |
+
+## 使用示例
+
+### 1. 基础用法 (水平排列)
+
+```vue
+<ButtonGroup
+  :links="[
+    { label: '查看详情', id: 'detail' },
+    { label: '下载资源', id: 'download', type: 'download' }
+  ]"
+  @click="(e, item) => console.log('点击了:', item.id)"
+/>
+```
+
+<ButtonGroup
+  :links="[
+    { label: '查看详情', id: 'detail' },
+    { label: '下载资源', id: 'download', type: 'download' }
+  ]"
+  @click="(e, item) => console.log('点击了:', item.id)"
+/>
+
+### 2. 垂直排列与尺寸控制
+
+```vue
+<ButtonGroup
+  layout="vertical"
+  size="l"
+  :links="[
+    { label: '选项一', icon: 'settings' },
+    { label: '选项二', icon: 'person' }
+  ]"
+/>
+```
+
+<ButtonGroup
+  layout="vertical"
+  size="l"
+  :links="[
+    { label: '选项一', icon: 'settings' },
+    { label: '选项二', icon: 'person' }
+  ]"
+/>
+
+### 3. 混合图标与文本
+
+```vue
+<ButtonGroup
+  size="m"
+  :links="[
+    { id: 'prev', icon: 'chevron_left', ariaLabel: '上一页' },
+    { id: 'index', label: '1 / 5', color: 'tonal' },
+    { id: 'next', icon: 'chevron_right', ariaLabel: '下一页' }
+  ]"
+/>
+```
+
+<ButtonGroup
+  size="m"
+  :links="[
+    { id: 'prev', icon: 'chevron_left', ariaLabel: '上一页' },
+    { id: 'index', label: '1 / 5', color: 'tonal' },
+    { id: 'next', icon: 'chevron_right', ariaLabel: '下一页' }
+  ]"
+/>
+
+### 4. 链接跳转
+
+```vue
+<ButtonGroup
+  target="_blank"
+  :links="[
+    { label: 'GitHub', link: 'https://github.com', icon: 'code' },
+    { label: '首页', link: '/', icon: 'home' }
+  ]"
+/>
+```
+
+<ButtonGroup
+  target="_blank"
+  :links="[
+    { label: 'GitHub', link: 'https://github.com', icon: 'code' },
+    { label: '首页', link: '/', icon: 'home' }
+  ]"
+/>
