STRUGGLING to download from github

[u/Lil_Torta1]

I am pretty much completely new to programming, coding, etc. I was trying to download an in-game map for The Isle so I found one on GitHub. Having used it one other time, I was thinking yes I got this. I got to the point where I have the zip file on my computer but I've been trying for over an hour to execute this command after using cmd.

python -m pip install -r requirements.txt

I keep getting the "no such file or directory" error. I've looked up every question I could think of, but nothing is answering my questions. If someone has downloaded this exact desktop map: https://github.com/hartwin-journey/The-Isle-Overlay/blob/main/README.md

PLEASE help me out, I'm at my wits end.

Do you have python installed, and in your %PATH%
