Gitbash is a terminal that you use to execute "git" commands and its highly recommended that you download it
Use the following link https://git-scm.com/downloads
Make a folder on your local drive (I make a folder on my desktop)
go into that folder and right click and open gitbash at that location
find the green button in the github that says "Code"
