+
+### About
+I wanted to add restart and shutdown options to XDM screen, but wasn't happy with the solutions I found. So I came up with this...
+
+Polybar for the menus and time. Picom (compton) for shadows and transparency on xlogin window and polybar. And feh provides random backgrounds each time XDM starts.
+
+NOTE: Does not include backgrounds (see [here](https://github.com/jeffmhubbard/antsy-wallpaper/)).
+
+### Requirements
+- [XDM](https://www.x.org) - X Display Manger
+- [polybar](https://github.com/polybar/polybar) - menu and clock
+- [picom](https://github.com/yshui/picom) - transparency and shadows
+- [feh](https://feh.finalrewind.org) - set background
+- [Nerd Fonts](https://www.nerdfonts.com/) - fonts with glyphs
