Edit the header of my web chat application built on Node, PHP and ES6 JavaScript on the frontend using [login to view URL] for websocket communication. Current version found here: [login to view URL] I do not have instructions for the current version, nor did I make it so you'll need to be able to figure out what the last programmer has done and simply add to his work. I've created a simple design guide (and not an exact design, you still need to add icons etc) but basically we are enlarging the header and adding a few extra buttons. Its not a big job, but there is a possibility of future work with me and this website.
