+## Setup
+Clone this repo to your desktop and run `npm install` to install all the dependencies.
+
+You might want to look into `config.json` to make change the port you want to use and set up a SSL certificate.
+
+---
+
+## Usage
+After you clone this repo to your desktop, go to its root directory and run `npm install` to install its dependencies.
+
+Once the dependencies are installed, you can run  `npm start` to start the application. You will then be able to access it at localhost:3000
+
+To give yourself administrator permissions on the chat, you will have to type `/role [your-name]` in the app console.
