This is a leightweight window manager configuration using i3-gaps, i3-radius, and polybar. As is, its configured for the X.org window system. Yet Xresources variables aren't utilized. Instead, everything can be modified via the config files.
I configured this on a fresh Ubuntu 20.04.3 LTS x86_64 on Linux 5.13.0-27-generic.
However, the programms used such as polybar, i3-radius, i3-gap, compton, lxappearance, or arandr are available in many other Distros, either from source or from the repositories.

foo@bar:~$ git clone https://github.com/firecat53/networkmanager-dmenu.git && cd networkmanager-dmenu/ && sudo cp networkmanager_dmenu /usr/bin/After entering the above commands, follow polybar installation instructions, i3-gaps installation instructions and compile i3-radius from source using the build.sh script that is in the submodule.
Copy the content of the config folder into your ~/.config/ folder, and do the same for fonts and icons.
Reboot, login.
