Am I understanding webpack correctly?

Question

JavaScript

I use webpack and vuejs.
The question is, did I understand correctly that every time I add a page, I have to add the entry point and the page itself to the config manually?

new HtmlWebpackPlugin({
      filename: 'index.html',
      template: 'index.html',
      inject: true
    })

Answer 1

How many instances of HtmlWebpackPlugin - so many pages. I don't understand much about the entry point.
