Your instructor chose well!
My best advice to a beginner is to follow this guide:
https://wiki.fogproject.org/wiki/index.php?title=Fedora_21_Server
But, instead of Fedora 21, use either CentOS 7 or Fedora 23. if you use Fedora 23, replace yum with dnf in all the commands that use yum - and you’ll be good to go.
If you need any help, don’t hesitate to post again. We like helping newbies who want help 🙂
