In plain English

Homebrew Core is a curated catalog of installable software for macOS. It powers the command brew install, which lets you install apps and developer tools from your terminal instead of downloading installers from websites. When you run brew install <something>, Homebrew looks up the corresponding "formula" in this repository. A formula is essentially a recipe written in Ruby that tells Homebrew where to download the software, how to build it, and where to put it on your system. This repository contains thousands of those recipes, covering everything from command-line utilities to programming languages. This is primarily for developers, data scientists, and power users working on Macs. If you need Python, Node.js, PostgreSQL, or terminal tools like wget, you can install any of them with a single command. It also makes keeping your software updated easy, since brew upgrade handles everything at once. The repository also works on Linux and Windows Subsystem for Linux, though those users would use a separate catalog. Beyond that distinction, the README doesn't go into much detail, pointing instead to the main Homebrew documentation for troubleshooting, contributing, and community information.
