Why would anyone build with this?

REASON 1

Build the Go toolchain from source on a platform that has no prebuilt binary available.

REASON 2

Contribute a bug fix or new feature to the Go language itself by following the project's contribution process.

REASON 3

File a well-formed bug report or feature proposal against the Go language using the official issue tracker.

Building Go from source requires an existing Go bootstrap toolchain and is intended for contributors, not everyday Go users who should use prebuilt binaries.

Use freely for any purpose, including commercial use, with minimal restrictions, just keep the copyright and license notice (BSD-style).

Wtf does this do

golang/go is the official repository for the Go programming language, an open source language designed to make it straightforward to build software that is simple, reliable, and efficient. If you have ever felt that setting up or writing a program was more complicated than it needed to be, Go aims to reduce that friction by offering a language that is clean and predictable. This repository is the authoritative source for Go itself, mirrored from the project's own infrastructure at go.googlesource.com. It contains the language's source code, and anyone who needs a version of Go that doesn't have a ready-made binary for their system can build it directly from this source. For most people, pre-built binary packages are available for download and are the recommended way to get started. Go is released under a BSD-style open source license, which allows broad use and redistribution with minimal restrictions. The project is maintained by thousands of contributors. If you want to help, the project points to official contribution guidelines, and uses its issue tracker specifically for bug reports and feature proposals rather than general questions. In short, this repository is for developers who want to understand how Go itself is built, contribute to the language, or compile it from source. Everyday users of Go typically just download a binary release and start writing programs.

Yoink these prompts

Prompt 1
Help me build the Go toolchain from the golang/go source code on an ARM Linux device where no prebuilt binary exists.
Prompt 2
Walk me through the Go contribution process step by step: how do I clone the repo, make a change, run tests, and submit a patch for review?
Prompt 3
Show me the folder structure of the golang/go repository so I know where the compiler, runtime, and standard library source files live.
Prompt 4
I found a bug in the Go standard library, what information do I need to include in a useful issue report on the golang/go tracker?
