+Welcome to Elixir School's workshop on Real-Time Phoenix with Channels, PubSub, Presence and LiveView! This application exists to guide workshop participants through each of these topics by allowing them to build out a set of features to support a fantastically fun game of "pointing party".
 
 Collaborators can sign in with a username and click a button to start the "pointing party". Tickets are displayed for estimation and each user can cast their store point estimate vote. Once all the votes are cast, a winner is declared and the participants can move on to estimate the next ticket.
