Hi Joel,
Sorry for this late reply.
ROOT is a large system serving many different types of application.
Guidelines to start with the system depend on what you want to do.
I can only recommend reading:
- The introductory tutorials
http://root.cern.ch/root/Howto.html
http://www-pat.fnal.gov/root/
- The Users Guide
http://root.cern.ch/root/RootDoc.html
- See examples of applications:
