+## Mobile application with Ionic
+
+[Ionic](https://ionicframework.com/docs/) is a toolkit for building cross-platform mobile applications from web applications. We have a [minimal chat mobile application](https://github.com/GetStream/ionic-angular-chat-app) using our SDK and Ionic to showcase how you can use the two together (please note that push notifications are not yet implemented for the sample application, and we don't yet have a guide for Ionic, but our [push notification guide](https://getstream.io/chat/docs/javascript/push_introduction/?language=javascript) can get you started).
