	Welcome to the configuration script for your virtual (or not) machine
	Before the script starts and you are ready to use the VM one warning
	RTFM! Often the question your asking has been forecasted by the ones
	who developped the tool you're now using and more often than not the
	answer is in the doc.
	Don't forget to upgrade your system to the latest version too
	If zsh is not your login shell after running the script
	run : "chsh -s \$(which zsh)"
	You can also add the plugin "colored-man-pages" to your .zshrc
	(should be around line 73)
	Write an email to nsainton@student.42.fr in case of trouble.
	Now I wish you the best programming experience
	GREETINGS
