You can install ZSH using Pacman
sudo pacman -S zsh
grml-zsh-config` zsh distribution is a similar to `
sudo pacman -S grml-zsh-config
If you prefer oh-my-zsh you can install that too.
curl -L http://install.ohmyz.sh | sh
Now we have ZSH installed. If you have any problem feel free to leave a comment below.
