 DDS Example
 ===========
 
-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 the one in Example 1-n-1, but now it can be easily distributed on different computing nodes without the need for manual addresses reconfiguration of the devices.
+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 socket reconfiguration of the devices.
+
+To make use of DDS functionality the example executables need to find the DDS plugin libraries that are compiled with FairRoot when FairRoot find DDS installed. Custom DDS location can be given to CMake as follows:
+
+```bash
+cmake -DDDS_ROOT="/path/to/dds/install/dir/" ..

 The description below outlines the minimal steps needed to run the example with DDS. For general DDS help please refer to DDS documentation on [DDS Website](http://dds.gsi.de/).

 ##### 3. Write DDS topology file that describes which tasks (processes) to run and their topology and configuration.
 
-Take a look at `ex-dds-topology.xml`. It consists of a definition part (properties, tasks, collections and more) and execution part (main). In our example Sampler, Processor and Sink tasks are defined, containing their executables and exchanged properties. The `<main>` of the topology uses the defined tasks. Besides one Sampler and one Sink task, a group containing Processor task is defined. The group has a multiplicity of 10, meaninig 10 Processors will be executed. Each of the Processors will receive the properties with Sampler and Sink addresses.

 ##### 8. (optional) Use example command UI to check state of the devices
 
-A simple utility (fairmq-dds-command-ui) is included with FairMQ to send commands to devices and receive replies from them. The utility uses the DDS intercom library to query state/config of devices and allows changing their state. To let the device listen to the commands from the utility, start the device with `-S "<@FAIRMQ_INSTALL_DIR@/lib" -P dds` cmd option (see example XML topology).
+A simple utility (fairmq-dds-command-ui) is included with FairRoot to send commands to devices and receive replies from them. The utility uses the DDS intercom library to send "check-state" string to all devices, to which they reply with their ID and state they are in. The utility also allows requesting state changes from devices. To let the device listen to the commands from the utility, start the device with `-S "<@FAIRROOT_INSTALL_DIR@/lib" -P dds` cmd option (see example XML topology).
 
-To see it in action, start the fairmq-dds-command-ui while the topology is running. Run the utility with `-h` to see everything that it can do.
-
-The utility requires a session parameter to connect to appropriate DDS session. The session value is given when starting dds-server.
-
-By default the command UI sends commands to all tasks. This can be further refined by giving a specific topology path via `-p` argument.
-Given our topology file, here are some examples of valid paths:
-```bash
-# get state of all devices
-./fairmq/plugins/DDS/fairmq-dds-command-ui -s 937ffbca-b524-44d8-9898-1d69aedc3751 -c c
