Config process fails on windows

[ArtificialIntelliGents]

The config script process failed in multiple ways when I tried to execute it.
I was putting together a pull request but noticed there were likely other errors and decided someone with more familiarity would need to address and redesign the configuration process. I can't say how deep the rabbit hole goes, and can't say I'd be able to get the project to work.

I am using VSCode on Windows 11.
I have been learning the basics for a few weeks and decided to take things to the next level.
I am able to edit and run a basic scaffold project, so my basic environment is probably fine.

• The first error presented to me was In setup_github.rb. Line 26 fails because the command needs to be "start" for windows.
• • I was able to correct this issue with :

elsif Gem::Platform.local.os == "mingw"
      "start"

• This created a problem where the configuration failed part way through and continued to fail because the README.example.md file was delete.
• • This can be fixed with :

if !File.file?(file)
    return
  end

• • At minimum the documentation should mention that any failure in the process requires the user to reclone the repo and start over.
• • ideally the config process should track the progress and write any input to a temp file, allowing the configuration to be continued in case of a failure.
• • But if that is outside the scope of the project file existence should be checked before manipulation.
• It also created a problem where the repo was created on GitHub and checked in locally, but the process continued to ask me if I wanted to create a repo and commit changes.
• • this created a weird state where HTTP_PATH would not be defined when I wanted to add a render deploy button because I would chose not to create a github repo.
• • I got around that by changing deploy_button_render.rb

new_repo_link = if defined?(SETUP_GITHUB) && defined?(HTTP_PATH)

At this point I was able to complete the configuration.
But have no idea if it is correctly configured.

I then took a look around the folder and saw the check_yarn.rb file and didn't remember the configuration process checking for Yarn.
I don't think the following works on windows.

if `yarn -v 2> /dev/null`.length > 0

Anywhere that checks for an installed file should have a windows specific check.
I think the following would be correct,

command = if Gem::Platform.local.os == "mingw" ? "where.exe Yarn > NUL 2>&1" : "yarn -v 2> /dev/null"
if `#{command}`.length > 0
  puts "Yarn is installed.".green
else

I'm new to rails so I'm not familiar with cross platform support,and without a mac I can't claim any of my changes are correctly written for cross platform compatibility. Being new to rails means I can't confirm if the configuration is in a valid state, so any more research and edits done by me would likely be futile. If the I didn't spend the last 2 hours running into problems I would have been more confident to make a PR. Without the ability to know I am in a stable environment I am not willing to move forward with making a fix,

Additionally I ran into a problem yesterday, where I can't install the bullet_train gem because charlock_holmes won't install. The only instructions available in your documents require using homebrew, which isn't cross platform as far as I am aware. So I wouldn't be able to use the gem in place of the repo either.
