GIT install
Look after whether git has been installed ~ you have git on your local machine. Type in command line (henceforth cmd:)
If results are empty, or inapprotiate result: you need install git from the git's main website. This will install also the GitBash command line for git commands together with the git itself!
GIT command arguments
The git command arguments e.g. git --help or git help, can be used on both way because of an internally latter gitversion convertion.
