TL;DR Many SaltyVagrant articles and books use a common set of tools. This article outlines the tools used.

You will need to install three tools to your computer:

  1. virtualbox—to run virtual machines.
  2. vagrant—to supervise the creation and setup of virtual machines.
  3. git—for version control (and more immediately to get the files needed to setup the virtual machines).

The installation instructions for these tools tend to vary over time so it’s best if you visit the websites, download the tool and follow the installation instructions relevant to your computer’s operating system.
