 To test this app on your local server:
 - The Ratchet server must be ON. This can be achived by navigating to *__webrtc-ratchet-chat-app/ws/bin__* from your cli and run *__php server.php__*
 - Run the app from your browser at: `http://localhost/webrtc-ratchet-chat-app/`
-- Create a room and get link to room
-- Open the links from two different browsers and test by sending text chats
+- Create and enter a room
+- Enter the room from two different browsers (using the same link) and test by sending text chats. This can be done on the same device.
 - The audio and video call is best tested on two different devices. This will require more configuration
  - Open `webrtc-ratchet-chat-app/config.php` and change this line `define('WS_URL', 'ws://localhost:8080/comm');` to `define('WS_URL', 'ws://YOUR_SERVER_IP:8080/comm');`
  - Open __`webrtc-ratchet-chat-app/ws/bin/server.php`__ and add your server `ip address` to __`$allowed_origins`__ array, then replace the `localhost` in `$app = new Ratchet\App('localhost', 8080, '0.0.0.0');` with your `ip address`
