+Requires docker to be installed. While the CLI is sufficient to complete this tutorial, Docker Desktop offers a lot of useful features. Instructions for downloading and installing Docker and/or Docker Desktop can be found [here](https://docs.docker.com/desktop/). You should enable docker to utilizes ~60 GB of VM memory, enabling as much swap that fits within your system. This tutorial was tested and validated on a machine with 34.4GB RAM and 1TB of disk where docker VM was permitted 60GB VM memory and 100GB swap space.
