Setting up Absence Entitlements and Takes

We're attempting to implement PS HRMS/Global Payroll (USA) without the aid of a consultant and are having a hard time understanding how to set-up our leave rules in Peoplesoft Global Payroll.  We understand it should be done through absence entitlements and takes, but do not understand the documentation in the Peoplebooks about this topic.  Does anyone have a good resource to look at other than peoplebooks to explain setting up absense entitlements and takes? Or even sample data that they'd be willing to share?
