prompt

The problem

Users installing Spaceship via homebrew don't know they have to add following lines to their .zshrc:

autoload -U promptinit; promptinit
prompt spaceship

Describe the solution you'd like

Homebrew has to report a caveat with this information. Here's an example how they do that with nvm formula: https://github.com/Homebrew/homebrew-core/blob/23f6654873c
