+An extensive list can be found in our [.browserlistrc](https://github.com/mui-org/material-ui/blob/next/.browserslistrc#L12-L27) (check the `stable` entry).
 If you need to support IE 11, check out our [legacy bundle](/guides/minimizing-bundle-size/#legacy-bundle).
 
 Because Googlebot uses a web rendering service (WRS) to index the page content, it's critical that Material-UI supports it.
