    +# Apache ActiveMQ Artemis Addressing and Queues
    +Apache ActiveMQ Artemis has a unique addressing model that is both powerful and flexible
and that offers great performance. The addressing model comprises three main concepts: addresses,
queues and routing types.
    +An address represents a messaging endpoint. Within the configuration, a typical address
is given a unique name, 0 or more queues, and a routing type.
    +A queue is associated with an address. There can be multiple queues per address. Once
an incoming message is matched to an address, the message will be sent on to one or more of
its queues, depending on the routing type configured. Queues can be configured to be automatically
created and deleted.
    +A routing type determines how messages are sent to the queues associated with an address.
A Apache ActiveMQ Artemis address can be configured with two different routing types.
    +Table 1. Routing Types
    +| If you want your messages routed to…​	                                   | Use
this routing type …​ |
    +| :----------------------------------------------------------------------: | :---------------------:
    +| A single queue within the matching address, in a point-to-point manner.  | Anycast
    +| Every queue within the matching address, in a publish-subscribe manner.  | Multicast
    +**Note:** It is possible to define more than one routing type per address, but this typically
results in an anti-pattern and is therefore not recommended.  If an address does use both
routing types, however, and the client does not show a preference for either one, the broker
typically defaults to the anycast routing type.
    +The one exception is when the client uses the MQTT protocol. In that case, the default
routing type is multicast. |

    IMO, this section would be better near the bottom of the document. It gets into the implementation
weeds a bit.
