 ### What is a Voxa Node?
 
 A voxa node is a server that handles DMs sent to you and push message notifications, a client will keep a constant connection with their chosen node and when a sender wants to send a DM or a message notification they can make a HTTP request to the same port, it's important to note that a node server only handles the receiving side, unless both parties are in the same node.
