I wanted to install i3 gaps on debian stable. My recommendation is to install debian stable minimal (no gui). I used the expert method.
sudo apt install git
git clone https://github.com/drewgrif/i3gaps-debian
cd i3gaps-debian
./install.sh (includes nerdfonts.sh and copyconf.sh unless commented)
OPTIONAL: Nerd Fonts installed by default but can be commented out of install.sh
# source ~/i3gaps-debian/nerdfonts.sh
OPTIONAL: Customized configuration installed by default but can be commented out of install.sh
# source ~/i3gaps-debian/copyconf.sh
NOT OPTIONAL
sudo reboot
