+
+## 使用场景:
+
+左侧 link 高亮显示当前 container 中显示的 content。
+点击触发 link 时，container 内平滑滚动至 link 绑定的 content。  
+提供 scrollTo 方法支持控制滚动到指定的 content。
+支持 content 内嵌自定义内容。
+
+## 使用限制:
+
+container 必须是可滚动的。
+如果滚动到底部，scrollHeight - scrollTop === clientHeight，则默认选中最后一个 content。
+
+## 基本使用方式:
+
+```html
+<!-- links -->
+<aside>
+  <a auiTocLink="content1" [for]="toc">content1</a>
+  <a auiTocLink="content2" [for]="toc">content2</a>
+  <a auiTocLink="content3" [for]="toc">content3</a>
+</aside>
+<!-- scroll container -->
+<article auiTocContainer #toc="auiTocContainer">
+  <section auiTocContent="content1">...</section>
+  <section auiTocContent="content2">...</section>
+  <section auiTocContent="content3">...</section>
+</article>
+```
+
+## 样式设置
+
+可以在 css 中为 link 和 content 设置 ‘.isActive’, 指定当 link 和 content 被选中时的样式。
