A real-time chat app is a software application that allows users to communicate with each other in real-time through text, voice, or video. A README file for such an app would typically include the following information:

Introduction: A brief overview of the app and its features.

Steps to Start the App

Installation:

Install the Public Dependencies

Install the Server Dependencies

In the Server Directory there's a .env file. Change the value of mongodb inside the file. Set the value as your mongodb connection url.

Now start the server by npm start

Now start the react by npm start

And the chat application would be running successfully by now.
