IntelliJ edu course creation tool updates these files and removes the license. Whenever one updates anything in the course files, they would have to manually update the license information. These files only store metadata about the course.

Makes sense! Lets not fight IntelliJ here, it's not a good use of anyone's time.

LGTM Thanks for the update! Fixing the imports to reflect the production usage is most excellent.

The SDK has triggers now, and in 2.42.0 it looks like we'll have State, if not timers, so the course can expand! But we most certainly want to wait for a slightly easier to use, portable Go runner before having a stand alone kata course demo those features.

@lostluck Thank you so much for reviewing this! We are in the process of building Tour of Beam. So perhaps we can add course content there.
