The command line can be a scary place for beginners, but there are only a handful of commands you'll need to know in order to use it.

On Mac you can go to spotlight "Terminal" and add to your dock.
On PC you can search for GitBash (a program that comes with Rails installer).

Learn the basic commands

$ pwd # Short for print working directory. Also, this is a comment.
$ open . # or start . on a PC
$ ls # Short for list
$ ls -a # Shows you hidden files and folders
$ cd Desktop # Short for change directory
$ cd ~ # Takes you back to your home folder
