 In addition to this core functionality FairMQ provides a framework for creating "devices" - actors which
 are communicating through message passing. FairMQ does not only allow the user to use different transport but also to mix them; i.e: A Device can communicate using different transport on different channels at the same time. Device execution is modelled as a simple state machine that

 ## 1-n-1
 
 A simple topology of three device types - **Sampler**, **Processor** and **Sink**. **Sampler** sends data to one or more **Processor**s, who modify the data and send it to one **Sink**. Transport with the **PUSH-PULL** pattern. The example also shows the configuration via JSON files, as oposed to `--channel-config` that is used by other examples.
 
+## Built-in devices
 
-## DDS
-
-This example demonstrates usage of the Dynamic Deployment System ([DDS](http://dds.gsi.de/)) to dynamically deploy and configure a topology of devices. The topology is similar to those of Example 2, but now it can be easily distributed on different computing nodes without the need for manual reconfiguration of the devices.
-
+Usage of generic devies provided with FairMQ.
 
 ## Copy & Push
 
 A topology consisting of one **Sampler** and two **Sink**s. The **Sampler** uses the `Copy` method to send the same data to both sinks with the **PUSH-PULL** pattern. In countrary to the **PUB-SUB** pattern, this ensures that all receivers are connected and no data is lost, but requires additional channels to be configured.

-This topology contains two devices that communicate with each other via the **REQ-REP** pettern. Bidirectional communication via a single socket.
+## Multipart
 
+This example shows how to send a multipart message from one device to the other. (two parts message parts - header and body).
 
 ## Multiple Channels
 
 This example demonstrates how to work with multiple channels and multiplex between them.
 
+## Multiple Transports
 
-## Sending Multipart messages
+This examples shows how to combine different channel transports (zeromq/shmem) inside of one device and/or topology.

+## n-m
 
+A topology consisting of three layers of devices: synchronizer -> n * senders -> m * receivers.
 
-## Multiple Transports example
+## QC
 
-This examples shows how to combine different channel transports (zeromq/nanomsg/shmem) inside of one device and/or topology.
+A topology consisting of 4 devices - Sampler, QCDispatcher, QCTask and Sink. The data flows from Sampler through QCDispatcher to Sink. On demand - by setting the corresponding configuration property - the QCDispatcher device will duplicate the data to the QCTask device. The property is set by the topology controller, in this example this is the `fairmq-dds-command-ui` utility.
 
-## Region example
+## Readout
+
+Two example topologies of setups to be distributed to two kinds of nodes - detector readout node and processing node. Detector readout node contains readout process, data builder and data sender (and optionally an additional processor), while processing node contains data receiver devices. communication within readout nodes is done via unmanaged region through shared memory transport.
+
+## Region
 
 This example demonstrates the use of a more advanced feature - UnmanagedRegion, that can be used to create a buffer through one of FairMQ transports. The contents of this buffer are managed by the user, who can also create messages out of sub-buffers of the created buffer. Such feature can be interesting in environments that have special requirements by the hardware that writes the data, to keep the transfer efficient (e.g. shared memory).

+This example demonstrates use of multiple transports (zeromq/shmem) within the same topology and/or device. It is a simple topology consisting of two samplers and a sink. The devices are connected via 3 channels:
 
 ![Multiple Transports example](../../docs/images/example_multiple_transports.png?raw=true "Multiple Transports example")
 
 Each device has main transport that it uses. By default it is ZeroMQ, and can be overriden via the `--transport` cmd option. The device will initialize additional transports if any of the channels have them configured (e.g. as an option to `--channel-config`).
 
-In this example sampler1 and sink are started with `--transport shmem`, making shared memory their main transport, sampler2 with `--transport nanomsg`. Additionally, the ack channel is configured to use zeromq as its transport.
+In this example sampler1 and sink are started with `--transport shmem`, making shared memory their main transport, sampler2 with `--transport zeromq`. Additionally, the ack channel is configured to use zeromq as its transport.
 
 The main two things that a transport does is transfer of data and allocation of memory for the messages. By default, new messages are created via the main device transport. If a message has been created with one transport and is to be transferred with another, it has to be copied into a new message of the target transport. This happens automatically behind the scenes. To avoid this copy the device can create messages via `NewMessageFor(const string& channelName, int subChannelIndex, ...)` method, that creates the messages via the transport of the given channel (check sampler1 and sink for an example) or as the channel directly to create a message.

+N-M
+==========================
+
+A topology consisting of three layers of devices: synchronizer -> sender(s) -> receiver(s). Senders distribute data to receivers based on the data id contained in the message from the synchronizer (same id goes to the same receiver from every sender). The senders send the data in a non-blocking fashion - if queue is full or receiver is down, data is discarded. Two configurations are provided - one using push/pull channels between senders/receivers, another using pair channels. In push/pull case there is only one receiving channel on the receiver device. In pair case there are as many receiver (sub-)channels as there are senders.

+QC
+==
+
+A topology consisting of 4 devices - Sampler, QCDispatcher, QCTask and Sink. The data flows from Sampler through QCDispatcher to Sink. On demand - by setting the corresponding configuration property - the QCDispatcher device will duplicate the data to the QCTask device. The property is set by the topology controller, in this example this is the `fairmq-dds-command-ui` utility.
