I designed, wrote and tweaked this Linux Mint Introduction course over a few months last year (Nov 2015) as a requested course I could run and teach personally at a community workplace. The topics covered are - in my view - about the most important general but practical areas for a single home user and/or a budding junior Sysadmin for a multi-user system to be introduced to and expand on in future, and immediately show the wide ranging capabilities of a linux system.
