In the public folder there is only one file that is important, that is index.html.This HTML file is a template.If you open it directly in the browser, you will see an empty page.You can add web fonts, meta tags, or analytics to this file.The build step will place the bundled scripts into the <body> tag.To begin the development, run `npm start` or `yarn start`.To create a production bundle, use `npm run build` or `yarn build`.
