attempting to run RecATHON

[yakovo-dev]

Hello,
I am new to programming, and I am attempting to execute RecATHON.
So far, I found startrecathonserver.jar on recdb-postgresql\PostgreSQL\experiments directory.
I have executed it by using java -jar, but I have encountered this error that recathonconfig.properties is missing.
So, I created it without writing a code, and terminal prints as 'Server Listening!' once I executed it again.

I am not sure I am on right track and/or I don't know of next step.
How do I start to run RecATHON?
