# Measure zsh prompt latency with various themes:
#
# 1. Run the docker command.
# 2. Type `ZSH_THEME=XXX exec zsh` where `XXX` is a theme name such as
#    `agnoster` or `powerlevel10k/powerlevel10k`.
# 3. Type `zsh-prompt-benchmark` and press and hold ENTER until benchmark
#    results appear. It takes about 10 seconds.
