How to set "Docs" as the main page

I am using the theme template and I am trying to change the main page of my website.

That is, how do I remove the index page and replace it with the "Docs" page as the main page on my website?

1. Delete src/pages/index.js
2. Add the following to docusaurus.config.js

module.exports = {
  // ...
  presets: [
    [
      '@docusaurus/preset-classic',
      {
        docs: {
          routeBasePath: '/', // Set this value to '/'.
          homePageId: 'getting-started', // Set to existing document id.
          // ...
        },
      },
    ],
  ],
  // ...
};
