Plz help non-Intellj experts open, run, and investigate this project

[mattiasw2]

This is a poster child for Kotlin webserver development. So, you want us as quickly as possible be able to compile, run and investigate the two projects. I expect to be able do proper find-usage etc in both frontend and backend project. However, I can only get the gradle compilation working. Inside Intellj, it just says I need to select the right JDK in yet another place :-)

After a while, I manage with a lot of trial and error go to the Rpc.kt and do find usage of the login function. Nice!

Next step is to check if the static typing really works.

Is there a video, or article somewhere that describes how to use Intellj in the best way to develop an application like this?
