Whether you use bash, zsh, or most any other shell, back up your configuration files. On almost any internet-connected system, I'm three steps away from my setup:

1. Install prereqs with package manager (curl, git, zsh, vim)

2. Download and install oh-my-zsh

3. Pull .zshrc, .vimrc, etc. from Github

4. (optional) Add workarounds because Windows Terminal still can't handle color and cursor position codes.
