Prep for theme - install nerd fonts

wget -O /usr/share/fonts/MesloLGS%20NF%20Regular.ttf https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Regular.ttf
wget -O /usr/share/fonts/MesloLGS%20NF%20Bold.ttf https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Bold.ttf
wget -O /usr/share/fonts/MesloLGS%20NF%20Italic.ttf https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Italic.ttf
wget -O /usr/share/fonts/MesloLGS%20NF%20Bold%20Italic.ttf https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Bold%20Italic.ttf

Alternately, use this bash script to install the fonts in one go:

sudo sh -c "$(curl -fsSL https://gist.githubusercontent.com/fullmetalbrackets/5a094e7daef47dd63074259143466442/raw/86f1cb332dda8976fddd371d3cf2530e48e031c9/meslo-fonts.sh)"

Install powerlevel10k theme

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

Using Zsh

Oh-My-Zsh install should have prompted to make Zsh the default shell. Logout and back in to use Zsh and initialize Oh-My-Zsh.

Configure theme

p10k configure

Done!

All your configuration will be saved in a .zshrc file in the user directory. Backup this file and in the future you can replicate this process with less steps, since your plugins and theme will already be preset -- just install Zsh, Oh-My-Zsh and the nerd fonts. (If using Powerlevel10k or another theme that requires them.)
