request to update the readme - please update sample with java run command #1

Hi Paul,

Can you please update your readme, so I can learn from your example. I get the following, I know I am missing the add module syntax from Java 9 and other specifics. It would be nice get some clarity on that if that is done via gradel then it will help as well.

C:\Users\prati\git\java9-vertx\easytext.web\build\scripts>easytext.web.bat
Error occurred during initialization of boot layer
java.lang.module.FindException: Module easytext.web not found

Regards,
Pratik Parikh
