wtf is ruby?

This repository is a fork of the official Ruby programming language repository. Ruby is a popular programming language known for being easy to read and write, it's often used to build web applications, automation scripts, and backend services. The README here is quite minimal, but what it shows is how to get Ruby set up and running. The single command provided (git show origin/HEAD:build | bash) is a way to automatically download and build Ruby from source code on your computer. Instead of manually typing out a bunch of installation steps, this one line does all the heavy lifting: it retrieves a build script and runs it automatically. This is useful if you want the very latest version of Ruby or need to customize how it's compiled for your specific system. You'd use this if you're a Ruby developer who wants to contribute to the language itself, test cutting-edge features before they're officially released, or maintain a custom version of Ruby for a specific project. Most everyday Ruby users would instead install Ruby from a pre-built package or version manager, but developers working on the language core or advanced use cases might need to build it this way. The README doesn't explain much beyond that initial setup command, so if you're looking for detailed documentation about what's changed or how to contribute, you'd likely need to check the main Ruby repository or look at the project's other documentation files.
