Jet Report for Excel Tutorial

If there is a better place to ask this question, let me know, but I am looking for a good tutorial/guide for Jet Reports for Excel. My new company uses this and I have tinkered with it some, but have not grasped all of the finer points yet. I found a few tutorials on YouTube, but they did not prove very useful. And as is typical, the documentation is very basic and not too helpful. Any suggestions would be appreciated.
