Installation - part 1: Jabber accounts

1. Register a Jabber account for your computer: using your favorite Jabber client create an account on any Jabber server (for example: MyHAL-home@jabber.org or John-laptop@jabber.org). This account will be used by MyHAL to log on the Jabber network.
   Don't have a Jabber client? Read the doc here (at least chapters 3.0 to 6.0)
   
2. Register a Jabber account for yourself: if you don't already have one, of course.
