This script is for MacOS and assumes you have homebrew and zsh installed. It could be modified to use bash and whatever package manager you're using on Linux. I'm not a shell script expert, so feel free to point out improvements / issues. Pro tip: using iTerm (or Tmux) create a vertical split for live preview.
