So what is it?

This is an experimental project that tries to build QUIC using the Go programming language. QUIC is a modern networking protocol originally developed by Google that aims to make internet connections faster and more reliable than traditional methods. It's the technology that makes web pages load quickly and helps avoid those annoying moments when a video call freezes or a webpage stalls while loading. The project is essentially a from-scratch attempt to implement this protocol. Rather than using an existing, polished library, the developer set out to write the underlying code that handles how data gets chopped up, sent across the internet, and reassembled on the other end. The README points to reference documentation from the Chromium project and Google, which are the original specs for how QUIC is supposed to work. Someone who might use this is a developer interested in learning how modern internet protocols are built. If you've ever been curious about what happens under the hood when your browser connects to a website, studying a project like this can be educational. It could also appeal to someone building networking tools in Go who wants to understand or experiment with the protocol at a low level. The README is unusually blunt, describing the effort as something that "probably will go nowhere." This is a personal, exploratory side project rather than a polished tool ready for production use. The developer links to reference materials but doesn't offer setup instructions, examples, or guidance, so anyone hoping to run or build on it would need to dig into the code themselves.

Copy-paste prompts

Prompt 1
I want to understand how the QUIC networking protocol works by studying this Go implementation. Walk me through the main files and explain how data gets chopped up and sent.
Prompt 2
Help me trace the code path in this Go QUIC project from when data is sent to when it is reassembled on the other end. Explain it like I am learning networking basics.
Prompt 3
I found this experimental QUIC-in-Go project with no docs. Help me figure out how to read the code and what concepts I need to understand to follow along.
