 # Dialogs
 
-This component uses [dialog element](https://www.w3.org/TR/2013/CR-html5-20130806/interactive-elements.html#the-dialog-element), which is only supported by Chrome and Opera currently. For other browsers, you need to include a [polyfill](https://github.com/GoogleChrome/dialog-polyfill) in your code.
