Initial Install

The initial install and setup of VirtualBox and Vagrant

Why vagrant?

This tool uses a base image to quickly clone a virtual machine, and saves time and resources in the process. It allows for a repeatable process, should you want to get more virtual machine environments after the course.

In the course, I am using MacOS, if you’re using Windows please use Git.
This will align things as closely as possible to using Unix/Linux and will ensure you have an SSH Client.

From working in construction to learning electrical on the job I convinced myself to pursue tech as a career despite a lack of a formal background.
I've worked in Information Security (Cybersecurity) for 4 years and am helping those that want to learn about the field in any way I can.
