I've been looking over the requirements for that application and I do not believe you will be able to use it if you are on shared hosting. It requires use of something called Juggernaut which utilizes node.js which is a server application. You cannot have persistent processes on shared servers. If you are on vps that is a different story.
That being said I can't give you instructions since I don't happen to be on vps so can't try installing it myself >.>
