I used to have a repo with scripts that "encodes" those change. Stuff like "setup-zsh.sh" and so on. On a new computer, I could just install git, clone the repo then run the scripts. I stopped doing that because I don't use new systems often enough to be worth it, and as someone else said it's also a good time to examine and improve your workflow.
