Due note video is about 1hr long.. explains differences between virtualization vs docker.. tells how to use docker in GUI (which is how i don't use it) and just goes in quite a bit of a detail on quite a of the basics of the overview of all the features of what it can do and the features... don't think it really explains how to installs any images or anything.. so obviously be prepared to youtube or search for further knowledge if you want to try any of this... also other images (containers) make docker easier via GUI to manage that don't need dockerdesktop like that have you install.. in this video... so world gets very deep and complicated... but fun...

like the newest project "winboat" is running a full blown windows installation in docker for linux users to use windows applications without issues..
