I am still a student learning so any indication of what folder code needs to be in of the ruby mvc set up and command line instructions thanks.
Think of your work space as a linux machine. You have a terminal and can pretty much do as you please.
I suggest looking up how to upgrade postgresql on linux(via google or your preferred search engine).
