Vaadin-on-Kotlin Guides for Vaadin 10

Vaadin 10 is based on Web Components as opposed to Vaadin 8 (which is based on a GWT-based customized widget system). The programming model tends to differ a bit from Vaadin 8, and that’s why there is a separate set of guides for Vaadin 8 and for Vaadin 10. Don’t worry though - Vaadin 10 still uses the component-oriented approach we love from Vaadin 8.
