How to export your vagrant boxes

Prepare a new machine so the newcomer is able to work as soon as possible, with all the development tools your team already uses.

That’s a boring task.

But Vagrant came to solve that problem, making our life A LOT easier. It provides a portable and reproducible development environment using virtual machines.
