Create React App creates a public directory for you with a few files in it. This is where static application assets go. It contains the following by default:

• favion.ico: This is the React logo that gets displayed in browser tabs. You'll want to replace this with something representative of your application before you ship.
• index.html: This is the HTML file that's served to browsers and the entry point of your React application.
• manifest.json: This is used by some mobile operating systems when the application is added to the home screen.
