+* Test account in telegram
+
+What is there in this module:
+
+* JVM part of this example is a server with simple static webapp sharing and bot which just gives the webapp button to open webapp
+* JS part is the WebApp with one button and reacting to chaged user theme and app viewport
+
+## How to run
