in plain english

Homebrew Core is the default collection of "formulae" for the Homebrew package manager. Homebrew is a popular tool for installing software on macOS (and Linux) from the command line, and a formula is a script that describes how to download, build, and install a particular piece of software. This repository contains the default set of those formulas -- the ones that come built into Homebrew automatically, without needing to add any extra sources. To install any package listed here, you simply run brew install <formula> in your terminal. The README notes that further documentation, contributing guidelines, and other details are maintained in the main Homebrew/brew repository.
