Core Apps or Modules

I have installed Drupal 7, but when I attempted to install Opigno, the auto-installer failed. I then downloaded Opigno from drupal.org (version 7-x.1.23) and uploaded it to my drupal modules area. I then went into the control panel/administration panel and found that I have roughly one gazillion Opigno modules to choose from. As a first time user working in a sandbox, I am certain I don't want absolutely every module enabled. When I downloaded the manual, it was full of a bunch of linux-type command-line things to do, which don't help me at all, as I'm a windows user. I'm installing this as a proof-of-concept for my company, and once operational, I'll be turning over its administration to the IT group. My question, as the subject intimates: Where can I find a list of basic functional modules to get Opigno-LMS up and running? I need only the actual classroom-type functions to begin with. I am not yet worried about the e-commerce side, as this is just a sandbox. I want to mostly be able to have video courses (based on Captivate), quizzes/tests, some support documentation, and maybe a whiteboard (not needed out of the box). Can anyone direct me to the proper resource, or - assuming the list is not extremely long - tell me what the core modules are? Thanks for reading, Don
