An example of a zsh startup file using Powerlevel10k, syntax highlighting & Git completion. Requires macOS & Homebrew to run.

.zshrc

# Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
# Initialization code that may require console input (password prompts, [y/n]
# confirmations, etc.) must go above this block; everything else may go below.
if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
  source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
fi

source /usr/local/share/powerlevel10k/powerlevel10k.zsh-theme

# To customize prompt, run `p10k configure` or edit ~/.p10k.zsh.
[[ ! -f ~/.p10k.zsh ]] || source ~/.p10k.zsh

# Use syntax highlighting
source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

# Use Git completion
