+## Multicast Service
+
 The [MulticastService](ms.md) is used to send DNS
 [queries](xref:Makaretu.Dns.MulticastService.SendQuery*) and 
 [answers](xref:Makaretu.Dns.MulticastService.SendAnswer*) over the link local network.
 It also listens for DNS [Messages](xref:Makaretu.Dns.Message) and raises either the 
 [QueryReceived](xref:Makaretu.Dns.MulticastService.QueryReceived) or [AnswerReceived](xref:Makaretu.Dns.MulticastService.AnswerReceived) event.
 
+## Service Discovery
+
 The [ServiceDiscovery](sd.md) is used to find services and service instances on the network.
 To advertise a service, simply create a [ServiceProfile](xref:Makaretu.Dns.ServiceProfile) 
 and then [Advertise](xref:Makaretu.Dns.ServiceDiscovery.Advertise*) it.  Any queries for the service or 
 service instance will be answered with information from the profile.
