This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

Afterwards, we'll see how easy it is to package our newly provisioned VM

	send_paranoid_instructions: "Если ваш адрес email есть в нашей базе данных, то в течение нескольких минут вы получите письмо с инструкциями по подтверждению вашей учётной записи."

	already_authenticated: "Вы уже вошли в систему."

	# You should see a message like:
	# [default] The guest additions on this VM do not match the install version of
	# VirtualBox! This may cause things such as forwarded ports, shared
	# folders, and more to not work properly. If any of those things fail on
	# this machine, please update the guest additions and repackage the
	# box.
