Little tweaks,improvements here and there as I find better ways of doing things but otherwise, it was not much work at all.
Install from a live CD...actual CD originally, USB these days, go to the options menu that has all the things, click some buttons and menus, drag some widgets around, browse through the shiny WM themes, download, install, done.
If you can use a computer to do basic tasks, it's really not hard. If you can't navigate some menus that have confusing titles like, desktop settings and themes and display options and widgets and you can't click and drag things around, whatever OS you use will be a struggle.
