Having a hard time to use hangups.js

[mike1011]

I need some help so that i can send/connect with any user having its id - google+ users.
Looking at the example below, i am confused what values will come in while starting the conversation-

Client = require 'hangupsjs'
Q      = require 'q'

# callback to get promise for creds using stdin. this in turn
# means the user must fire up their browser and get the
# requested token.
//****** WHAT IS THIS .DO I NEED TO PROVIDE USE EMAIL/PASSWORD
creds = -> auth:Client.authStdin

client = new Client()

# set more verbose logging
client.loglevel 'debug'

# receive chat message events
client.on 'chat_message', (ev) ->
    console.log ev

# connect and post a message.
# the id is a conversation id.
client.connect(creds).then ->
  //**** DONT UNDERSTAND WHAT TO SEND AS A PARAMETER TO SAY Hello World.Is it the google+ user id or email/password of the person to whom to send.Kindly clarify
    client.sendchatmessage('UgzJilj2Tg_oqkAaABAQ', [
        [0, 'Hello World']
    ])
.done()

my server log....dont know whats going on..i know browser is trying to open and then what ... ?
