### What is Homebrew?

Homebrew is a free and open-source package management system for macOS that simplifies software installation. It has become a popular tool among developers and system administrators for its ease of use and extensive package availability.

<Note>
  As with all scripts, please test thoroughly before deploying to Mac computers in production.
