 > Please post feedback to the [observatory-discuss group][discuss-list]
 
 This document describes _draft 1_ of _version 1.0_ of the Dart VM
 Service Protocol.  This protocol is used to communicate with a running
 Dart Virtual Machine.
 
 To use the Service Protocol, start the VM with the *--observe* flag.
 The VM will start a webserver which services protocol requests via WebSocket.
