Set Up Tutorial

Hi. Is there an easy place to find and tutorial/guide for setting up Quicken? I want to primarily use it for my small business finances/tax tracking and P&L, but I realize it would be good to also use it for my personal finances and tracking of home office and other expenses I can claim. I am just nervous about connecting other accounts and having things mixed. I'll I have done so far is the very basic account set up and connect my business checking account. I would appreciate any direction or guidance.

Thanks, Susanne
