-Please refer to the [example subdirectory](https://github.com/benthillerkus/betrayal/tree/main/example) for more [information](https://github.com/benthillerkus/betrayal/blob/main/example/README.md) and code.
+If you just want a tray icon, that's pretty much all you need to know.
+
+There is, however, also a quick-guide [README.md](https://github.com/benthillerkus/betrayal/tree/main/example), four example applications and of course the [API docs](https://pub.dev/documentation/betrayal/latest/betrayal/betrayal-library.html), if you do want to learn more.
+
+Don't hesitate to [file an issue](https://github.com/benthillerkus/betrayal/issues), I'll have a look at it eventually 😊
