Import .cpp based problem to domjudge?

Hello, I'm currently new in this field and want to ask a few questions regarding creating a problem on domjudge.

First of all, I have one problem and I want to add it to the domserver. I have the pdf (text) for the question and .cpp for the solution. What do i have to configure to add the problem to the server, what is the meaning of run and compare script, and how do I insert the .cpp solutions file to the problem?

Thank you!
