$ man homebrew
Engineering · Terminal and CLI
Homebrew
The Mac package manager. An app store for developer tools that runs from the terminal.

why it matters
Homebrew installs Git, Python, Node, and everything else developer tools depend on. Instead of downloading installers from websites, you type brew install and the tool appears. I learned Homebrew during my Mac Mini migration. Did not know what it was. Installed it anyway. Then installed Git, Python, Node. That experience became content. The learning was the content.
how you use it
brew install git installs Git. brew install python installs Python. brew update refreshes the package list. brew list shows installed packages. brew upgrade updates everything. Five commands cover 90% of Homebrew usage.
