The question: Do you want to automatically run the scripts that configure the package, then installing the dependencies?

When you selects the true value, the following scripts ubicated in the package.json are executed:

init
format:fix

If you selects the false value, if you want to use husky, you must run npm run init.

"init": Runs the commands necessary to initialize the package, for example init:husky.
"dev": Runs the application in development mode using nodemon and dotenv.
"start": Runs the application using node.
"format": Checks the format using prettier.
"format:fix": Fixes the format using prettier.
"lint": static code analysis using eslint.
