After the installation you can turn the prompt On or Off with `kubeon` or `kubeoff`

*   install `zsh`

    *   MacOS (it's there and OK)

    *   CentOS, RHEL, fedora: `sudo install -y zsh`

    *   Debian, Ubuntu, raspbian: `sudo apt install -y zsh`

    *   Windows? =Y You're kidding, use WSL2

*   change your login shell like: `usermod -s /bin/zsh $USER`

*   install ohmyz.sh: `sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"`
