What to do AFTER you've installed ARCH LINUX - beginner friendly post-install guide

A new-user friendly guide of basic steps to configure your minimal Arch Linux installation, from installing packages and upgrading your system to installing a desktop environment or window manager!

NOTE: #!/bin/sh will be necessary to run shell commands from your xprofile. You can add this in as the top line, it is called a "shebang" and it is used to instruct how the file should be parsed, directing to the default shell on your system.

Please bare with me as I get used to recording! If I do forget something while recording I will always make note in the description.
