Is the _ folder a MUST HAVE?

[GarfieldDeepClone]

Hi :)

I setup husky according to the "Get Started" guide here:
https://typicode.github.io/husky/get-started.html

My project structure is like this:

├── .git/
└── frontend/ # Package.json with husky

the init created a husky structure here:

frontend/.husky with a pre-commit file in it.

Because of the structure I changed the prepare script in package.json to:
"prepare": "cd .. && husky frontend/.husky"

and in my pre-commit file:

cd frontend
npx lint-staged

lintstagedrc.json:
{ "*.{js,ts,vue,html,css,scss,json}": "prettier --write" }

git config --get core.hooksPath
frontend/.husky/_

When I run npm run prepare it creates a frontend/.husky/_ folder with dozens of hooks in it. Why? Why doesn't this happen already with the husky init command? Do I nead frontend/.husky/pre-commit and frontend/.husky/_/pre-commit?

It seems like the prepare script is also setting the core.hooksPath always back to ui.frontend/.husky/_

So I don't understand why I need the prepare script and this _ folder? But it doesn't work without, when I change core.hooksPath to just frontend/.husky/ and deleting the _ folder I get this error message when commiting:
error: cannot spawn ui.frontend/.husky/pre-commit: No such file or directory

So my question is -> is this _ folder a MUST HAVE?
