Welcome to @Natemaia's guide for upgrading current installations. The contents of this guide should work for all current installs and will be updated, as required by each release.
The bulk of the upgrade process is automated but, there's still some work needed to be done depending which packages you install.
Ok, first we need to do some setup in order to install our packages and get the latest ~/.config/
This is automated, just clone the required repo and run the upgrade script.
