You can directly use this to help setup zsh

sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

or you can install the vanila setup us shown below

Install ZSH

sudo apt install zsh

Download or run this instead: https://github.com/ohmyzsh/ohmyzsh

Make it your default shell:

chsh -s $(which zsh)

Copy the .zshrc file from this repo and paste it in ~/.zshrc.

zsh
