2. Now we should create two new users, one for Live Helper Chat, let's call it lhcbot and another one remdex it will be us. So after you have done that you should see window identical to above
3. Now let's create a group chat where our lhcbot will send messages. For that navigate to "Group chat" from top menu and click create
   Here we fill Room ID, Room Name, Description, Topic and just click save.
   Make sure that you server points conference.xmpp.youdomain.com and xmpp.youdomain.com to your server IP
4. For testing purposes now you can download https://www.pidgin.im/ it's client for xmpp protocol. After you run first Click from top menu Accounts => Manage accounts and Add account. In add account page fill the form according to provided screenshot

   Don't forget to change host to your srever ip. Login - here we use previously created user lhcbot and set password. Also for testing purposes we set Individual recipient and test group recipient, we can separte by comma these recipients.
2. Now just click Send test message and in your pidgin you should receive two messages one for as individual recipient another one in Chat room named lhc. lhc@conference.xmpp.livehelperchat.com/lhcbot (<chat_group_name>@server.address/<bot_username>)
   
   Now you should see messages similar to above one. Pay attention that chat variables are not changed.
