 # Dart VM Service Protocol 0.0
 
 This document describes _version 0.0_ 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.
 It is possible to make HTTP (non-WebSocket) requests,
 but this does not allow access to VM _events_ and is not documented

 The _resume_ RPC is used to resume execution of a paused isolate.
 
 If the _step_ parameter is not provided, the program will resume
 regular execution.
 
 If the _step_ parameter is provided, it indicates what form of
 single-stepping to use.
