* Added some clarifying information
Added additional details about automatic discovery of the gateway on the network and how to configure it, found that many user have had to restart the gateway to get the configurator working, so also added a note about that
* Small changes
I needed to install an additional application for this to work so have added the command above.
This may not be the case for all, but is helpful to have all commands for completeness (at least i think so)
