Yeah I'm not saying its perfect and LLMs are non-deterministic so it could give you some crap. You're not wrong and it's good to be aware of that. How do you verify some random stranger from the internet wasn't an asshole and gave you malicious config? 🤷 The best answer is probably just that OP should heed the warning on the website they linked, if they have no confidence or relevant skills:

THIS IS DELIBERATELY MALICIOUS SOFTWARE INTENDED TO CAUSE HARMFUL ACTIVITY. DO NOT DEPLOY IF YOU AREN'T FULLY COMFORTABLE WITH WHAT YOU ARE DOING.

I pasted the OP unmodified into a local LLM and it gave me this:

Paste this (replace  192.168.1.105 with your Acer’s local IP from Part 1.3): 

server {
    listen 80;
    server_name wowsocool.com www.wowsocool.com;

    location / {
        proxy_pass http://192.168.1.105:8000/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

along with correct instructions on finding the IP of the laptop, port forwarding, and examples on how to set up DDNS for several popular providers. The only thing I can see that is wrong is the port should be 8893 instead of 8000 and they may want to proxy a different path to Nepenthes than /
