How it works
Step 1: Open the index.html file in any of your browsers.

How to modify?
Now to modify this chatroom, it is as simple as modifying any website!
index.html page is just a simple landing page where you can add a login page if you need or anything you like.
call.html is where you place the calling. There you can tweak to adjust the footage places and add further actions if needed.
script.js is the place where the main action takes place. Tweak it carefully to add further features in your room.
All tweaks can be done easily with the comments that are inside each file that easily understandable. Just go through it and let me know if further clarifications are needed!
