I am trying to start to use Bonjour. Here I found a manual how to register a service with Bonjour. The following is written there:

The network services architecture in Bonjour includes an easy-to-use mechanism for publishing, discovering, and using IP-based services.

Well let's see how to register a service. In the very beginning it is written:

To publish a service, an application or device must register the service with a Multicast DNS responder

But how?!?! First of all I do not know what is the Multicast DNS responder. Second, it is not written how do I do it. Where and what should I type? Should I use command line? Should I use some programming languages? What exactly should I type...

Is there an easy way to start to use Bonjour? Well, it was emphasized several times how easy it should be to use it. But I cannot start to use it for several day.

So, can anybody, pleas, help me with that?
