Report Builder tutorials

Hey everyone! I was put in a position with a data development group last year. We use ColdFusion and ColdFusion Report Builder for applications and reporting on our clients side. I've been recently working more and more with reporting as oppose to the ETL stuff I had been doing. I have found some tutorials on ColdFusion however when it comes to the Report Builder I find a lack of information on using this. Everything I've learned has been through trial an error modifying/working with already created reports. Are there any good resources out there I can use to get better at creating reports from the ground up?

We currently use a queries.cfc file that we link all of our reports to to find the underlying data queries but as far as being able to add new bands or really do more than just modifying existing contents....I'm at a loss. What resources does everyone recommend?

Thanks!!
