You should install [my dwm](https://github.com/dogeystamp/dwm), [dmenu](https://github.com/dogeystamp/dmenu), [slock](https://github.com/dogeystamp/slock) and [st](https://github.com/dogeystamp/st) builds as well as this for a complete desktop environment.
Also, the aesthetic is very minimal, so consider adding a wallpaper. Picom is already configured for blur/fading, but you should disable it if you wish to keep the black wallpaper.
