I tried AwesomeWM two days ago, and after two days of hard work understanding the API reference, I came up with this. More screenshots are below.
I had to look through the source code of their widgets (like wibox.widget.textclock, awful.titlebar.widget.maximizedbutton) they use in their default config file to have a grasp of what's happening. Looking through others' dotfiles was more pain because it's not supposed to be looked upon by the beginners, so they cram all they know in a few lines and leave you guessing.
