+
+<p class="description">The API documentation of the AvatarGroup React component. Learn more about the props and the CSS customization points.</p>
+
+## Import
+
+```js
+import AvatarGroup from '@material-ui/lab/AvatarGroup';
+// or
+import { AvatarGroup } from '@material-ui/lab';
+```
+
+You can learn more about the difference by [reading this guide](/guides/minimizing-bundle-size/).
+
+
+
+## Props
+
+| Name | Type | Default | Description |
+|:-----|:-----|:--------|:------------|
+| <span class="prop-name">children</span> | <span class="prop-type">node</span> |  | The avatars to stack. |
+| <span class="prop-name">classes</span> | <span class="prop-type">object</span> |  | Override or extend the styles applied to the component. See [CSS API](#css) below for more details. |
+
+The `ref` is forwarded to the root element.
+
+Any other props supplied will be provided to the root element (native element).
+
+## CSS
+
+- Style sheet name: `MuiAvatarGroup`.
+- Style sheet details:
+
+| Rule name | Global class | Description |
+|:-----|:-------------|:------------|
+| <span class="prop-name">root</span> | <span class="prop-name">.MuiAvatarGroup-root</span> | Styles applied to the root element.
+| <span class="prop-name">avatar</span> | <span class="prop-name">.MuiAvatarGroup-avatar</span> | Styles applied to the avatar elements.
+
+You can override the style of the component thanks to one of these customization points:
+
+- With a rule name of the [`classes` object prop](/customization/components/#overriding-styles-with-classes).
+- With a [global class name](/customization/components/#overriding-styles-with-global-class-names).
+- With a theme and an [`overrides` property](/customization/globals/#css).
+
+If that's not sufficient, you can check the [implementation of the component](https://github.com/mui-org/material-ui/blob/master/packages/material-ui-lab/src/AvatarGroup/AvatarGroup.js) for more detail.
