Wtf does this do

This project is a CHIP-8 emulator, a program that lets you run old CHIP-8 games and software on a modern computer. CHIP-8 is a simple, decades-old virtual machine that many programmers use as a first emulator project because its instruction set is small compared to real game console hardware. Based on the README, this emulator is split into two parts that run at the same time: a Python program, found at python/main.py, and a web page, found at html/index.html, that you open in your browser. The Python side starts a server, and it talks to the browser page using WebSockets, a technology that lets a server and a web page send messages back and forth continuously. So it seems the Python side likely handles running the CHIP-8 program itself, while the browser page is used to display it or interact with it, though the README does not spell out exactly which part does what. The README is very short and mainly explains that you need to start both the Python script and the browser page at the same time for the emulator to work. It does not list which CHIP-8 games are supported, does not mention a license, and does not describe how to install any dependencies the Python script might need before running it. There are also no screenshots, controls list, or troubleshooting notes included. Because the documentation is so limited, someone wanting to try this would need to read through the source code directly to understand dependencies, controls, and exactly how the Python and browser parts talk to each other beyond the basic WebSocket connection the README mentions.
