When migrating to a new computer, see section titled "Install your dotfiles onto a new system (or migrate to this setup)". Note that instead of .cfg, you should use .dotfiles in all the commands. You may also need to rename path in .zshrc if account name is different.
Use config add -u instead of config add -A since the latter will add untracked files.
