Installation and the dotfiles are to be managed with yadm, thus installation is done through cloning the repository using yadm clone, and then confirm running the bootstrapping script when prompted to. If not prompted after cloning, executing the bootstrapping script can be done at any time with yadm bootstrap.
Thus, if you have a completely fresh install of Arch Linux, do the following:
sudo pacman -S yadm
yadm clone https://github.com/Krismix1/dotfiles
yadm bootstrap- Configure SSH keys + hosts
- Update Polybar configuration for your environment (update network interfaces, battery module, backlight module)
