Based on: https://github.com/awesomeWM/awesome?tab=readme-ov-file#arch-linux-aur

First install the required packages:

sudo pacman -S --needed base-devel git
git clone https://aur.archlinux.org/awesome-git.git
cd awesome-git

Install LuaJIT:

asdf plugin-add luajit https://github.com/smashedtoatoms/asdf-luaJIT.git

sudo cp -r $HOME/.asdf/installs/luajit/2.0.5/share/lua/5.1/lgi /usr/share/luajit-2.1/lgi
