Hello. I wanted to follow steps to deploy this project but I'm having an error. Here are what I've done.

Description: I'm on Windows and I have downloaded Node.js by downloading zip file and installing it also did the same thing with Git(I don't know what is the difference with GitHub, I haven't used Git app. I don't know what is it for)
1- I have Vİsual Studio so I forked your project and renamed the for as my username.
2-Then I opened the fork and selected "open with Visual Studio" and then clone it.
3-I run this command "npm install --legacy-peer-deps" then I saw some errors.(did nothing)
4-I run "npm start" and everything is still fine.
5-I changed every file for myself and I can see the result on "http://localhost:3000/"
6-Everything is fine bu I'm getting an error while opening "http://localhost:3000/" this is the error " Compiled with problems:
