-## Installation
+## Introduction
+
+FairMQ is designed to help implementing large-scale data processing workflows needed in next-generation Particle Physics experiments. FairMQ is written in C++ and aims to
+  * provide **an asynchronous message passing abstraction** of different data transport technologies,
+  * provide a reasonably **efficient data transport** service (zero-copy, high throughput),
+  * be **data format agnostic**, and
+  * provide **basic building blocks** that can be used to implement higher level data processing workflows.
+
+The core of FairMQ provides an abstract asynchronous message passing API with scalability protocols
+inspired by [ZeroMQ](https://github.com/zeromq/libzmq) (e.g. PUSH/PULL, PUB/SUB).
+FairMQ provides multiple implementations for its API (so-called "transports",
+e.g. `zeromq`, `shmem` and `ofi` (in development)) to cover a variety of use cases
+(e.g. inter-thread, inter-process, inter-node communication) and machines (e.g. Ethernet, Infiniband).
+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
+shapes the integration points for the user task. Devices also incorporate a plugin system for runtime configuration and control.
+Next to the provided devices and plugins (e.g. [DDS](https://github.com/FairRootGroup/DDS))
+the user can extend FairMQ by developing his own plugins to integrate his devices with external
+configuration and control services.
+
+FairMQ has been developed in the context of its mother project [FairRoot](https://github.com/FairRootGroup/FairRoot) -
+a simulation, reconstruction and analysis framework.

+If your project shares a dependency with FairMQ or if you want to omit a certain dependency, you may want to customize the above example code to your needs.
 
 Optionally, you can require certain FairMQ package components and a minimum version:
 
 ```cmake
-find_package(FairMQ 1.1.0 COMPONENTS nanomsg_transport dds_plugin)
-find_package(FairLogger ${FairMQ_FairLogger_VERSION})
-find_package(Boost ${FairMQ_Boost_VERSION} COMPONENTS ${FairMQ_BOOST_COMPONENTS})

 ## 3.1 Device Configuration
 
-Devices receive configuration primarily via provided command line options (that can be extended per device).
+Device Configuration is stored in configuration object - `fair::mq::ProgOptions`. It is accessible by the device, plugins or from DeviceRunner/main:
+
+Plugins <---read/write---> ProgOptions <---read/write---> Device
+
+Whenever a configuration property is set, it is set in ProgOptions. Device/Channels/User code read this value and apply it as necessary at different stages:
+ - apply it immidiately
+ - apply it in device/channels during InitializingDevice/Binding/Connecting states
+
+Here is an overview of the device/channel options and when they are applied:
+
+| Property | Applied in |
+| --- | --- |
+| `severity` | immidiately (if `fair::mq::DeviceRunner` is used (also the case when using `<runFairMQDevice.h>`)) |
+| `file-severity` | immidiately (if `fair::mq::DeviceRunner` is used (also the case when using `<runFairMQDevice.h>`)) |
+| `verbosity` | immidiately (if `fair::mq::DeviceRunner` is used (also the case when using `<runFairMQDevice.h>`)) |
+| `color` | immidiately (if `fair::mq::DeviceRunner` is used (also the case when using `<runFairMQDevice.h>`)) |
+| `log-to-file` | immidiately (if `fair::mq::DeviceRunner` is used (also the case when using `<runFairMQDevice.h>`)) |

+![FairMQ state machine](images/device_states.svg "FairMQ state machine")
 
 The state machine can be querried and controlled via `GetCurrentStateName()` and `ChangeState("<state name>")` methods. Only legal state transitions are allowed (see image above). Illegal transitions will fail with an error.
 
 If the device is running in interactive mode (default), states can be changed via keyboard input:
 
  - `'h'` - help

+# 7. Plugins
+
+FairMQ devices can be integrated with external configuration and control systems through its plugin system. FairMQ plugins are special dynamic libraries that can be loaded at runtime. Plugins have access to the Plugin API which includes the capability to control/monitor the device [state machine](Device.md#13-state-machine) and change/monitor configuration properties.
+
+A simple plugin may add the feature to read configuration from a certain desired file format once at the start of a device. A more complex plugin may create a long-running thread that integrates a network client to an external API of a central experiment control system.
+
+Because plugins are loaded dynamically, they can be developed in separate repositories/projects and also have their own set of runtime dependency that are not needed to be known at compile-time of the FairMQ device.
+
+## 7.1 Usage
+
+To load a plugin pass the `-P <name>[,<name>]` (or long `--plugin`) command line option. Multiple plugins can be loaded at the same time. The load order is as specified at the command line. This determines the order in which the plugins are instantiated (ctor call order) and in which order they are notified, should they subscribe to any notifications.
+
+When passing `-h/--help` on the command line one can find more detailed information:
+
+```
+Plugin Manager:
+  -S [ --plugin-search-path ] arg       List of plugin search paths.
+                                        * Override default search path, e.g.
+                                          -S /home/user/lib /lib
+                                        * Append(>) or prepend(<) to default

+                                        here.
+```
+
+## 7.2 Development
+
+To develop a custom FairMQ plugin, one simply needs to inherit from the `fair::mq::Plugin` base class (`#include <fairmq/Plugin.h>`) and call the `REGISTER_FAIRMQ_PLUGIN` macro. It is possible to introduce new command line option together with a plugin.
+
+The Plugin API includes:
+  * `Take/Steal/ReleaseDeviceControl()`/`GetCurrent/ChangeDeviceState()`/`SubscribeTo/UnsubscribeFromDeviceStateChange()` APIs enable controlling the device state machine. Only one plugin is authorized to control at the same time. Which one is determined by which plugin calls `TakeDeviceControl()` first.
+  * `Set/GetProperty()`/`GetPropertyKeys()`/`SubscribeTo/UnsubscribeFromPropertyChange()` APIs enable configuration of device properties.
+See [`<fairmq/Plugin.h>`](/fairmq/Plugin.h) for the full API.
+
+A more complete example which may serve as a start including example CMake code can be found here: [FairRootGroup/FairMQPlugin_example](https://github.com/FairRootGroup/FairMQPlugin_example).
+
+## 7.3 Provided Plugins
+
+### 7.3.1 DDS
+
+When launching a FairMQ topology via [DDS](http://dds.gsi.de/) the DDS plugin enables FairMQ devices to interact with DDS' custom command and property subsystems - enable the plugin by passing `-P dds` on the command line.
+
+Via the property subsystem a FairMQ topology may exchange channel connection data (essentially to do service discovery) needed to connect/bind all FairMQ channels appropriately. DDS is highly optimized for this use case. See [examples/dds](examples/dds/README.md) for more details.
+
+Via the custom command subsystem a FairMQ device can receive a number of commands. FairMQ provides a convenient command line tool `fairmq-dds-command-ui` that allows interactive or scripted control of a running FairMQ topology managed via DDS. If one develops directly against the custom command DDS API, the following table lists all the commands the DDS plugin currently understands:
+
+| Custom Command | Response | Error | Description |
+| --- | --- | --- | --- |
+| `check-state` | `<ID>: <STATE> (pid: <PID>)` | n/a | Query current device state, see state machine for possible states |
+| `dump-config` | `(<ID>: <PKEY> -> <PVALUE>\n)+` | n/a | Query current device config (list property key/value pairs) |
+| `INIT DEVICE` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `BIND` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `CONNECT` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `INIT TASK` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `RUN` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `STOP` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `RESET TASK` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `RESET DEVICE` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `END` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `subscribe-to-heartbeats` | `heartbeat-subscription: <ID>,OK` | n/a | Subscribe to heartbeats |
+| on heartbeat subscription | `heartbeat: <ID>,<PID>` | n/a | Heartbeat every 100ms |
+| `unsubscribe-from-heartbeats` | `heartbeat-unsubscription: <ID>,OK` | n/a | Unsubscribe from heartbeats |
+| `subscribe-to-state-changes` | `state-changes-subscription: <ID>,OK` | n/a | Subscribe to state changes |
+| on state changes subscription | `state-change: <ID>,<STATE>` | n/a | State change notification |
+| `unsubscribe-from-state-changes` | `state-changes-unsubscription: <ID>,OK` | n/a | Unsubscribe from state changes |
+
+If unknown commands are received the plugin will print a warning.
+
+### 7.3.2 PMIx
+
+The [PMIx](https://pmix.org/) plugin enables launching a FairMQ topology with any PMIx capable launcher, e.g. the [Open Run-Time Environment (ORTE) of OpenMPI](https://www.open-mpi.org/doc/v4.0/man1/mpirun.1.php) or the [Slurm workload manager](https://slurm.schedmd.com/srun.html). This plugin is not (yet) very mature and serves as a proof of concept at the moment.

+# 8. Controller SDK
+
+The FairMQ Controller Software Development Kit (`-DBUILD_SDK=ON`) contains a (as of today still experimental) set of C++ APIs that provide essential functionality to the implementer of a global controller.
+
+The FairMQ core library only provides two local controllers - `static` (a fixed sequence of state transitions) and `interactive` (a read-eval-print-loop which reads keyboard commands from standard input). A local controller only knows how steer a single [FairMQ device](Device.md) - in fact, it runs in a thread within the device process.
+
+A global controller has knowledge about the full topology of connected FairMQ devices. Its responsibility is to facilitate the lifecycle of a distributed FairMQ-based application (*executing a topology*), such as
+
+* allocating/releasing compute resources from a resource management system,
+* launching/setting up the run-time environment and the FairMQ devices,
+* driving the device state machines in lock-step across the full topology,
+* pushing the device configuration,
+* monitoring (some aspects of the application's) operation,
+* and handling/reporting (some) error cases.
+
+The low-level hook to integrate FairMQ devices with such a global contoller is the [plugin mechanism](Plugins.md) in the FairMQ core library. The FairMQ Controller SDK provides C++ APIs that communicate to the endpoints exposed by such a FairMQ plugin.
+
+At the moment, the Controller SDK only supports [DDS](https://dds.gsi.de) as resource manager and run-time environment. A second implementation based on [PMIx](https://pmix.org/) (targeting its implementation in [Slurm](https://slurm.schedmd.com/documentation.html) and [OpenRTE](https://www-lb.open-mpi.org/papers/euro-pvmmpi-2005-orte/)) is in development.
+
+The following section give a short overview on the APIs provided.
+
+## RMS and run-time environment
+
+The classes [`fair::mq::sdk::DDSEnvironment`](../fairmq/sdk/DDSEnvironment.h), [`fair::mq::sdk::DDSSession`](../fairmq/sdk/DDSSession.h), and [`fair::mq::sdk::DDSTopology`](../fairmq/sdk/DDSTopology.h) are thin wrappers of most of the synchronous APIs exposed by DDS ([`dds::tools_api`](http://dds.gsi.de/doc/api-docs/DDS/html/namespacedds_1_1tools__api.html) and [`dds::topology_api`](http://dds.gsi.de/doc/api-docs/DDS/html/namespacedds_1_1topology__api.html)). E.g. they allow to [start a DDS session](https://github.com/FairRootGroup/FairMQ/blob/077eb0ef691940d764cfd1852bf3981dc812ddbd/main.cpp#L26-L28), [allocate resources](https://github.com/FairRootGroup/FairMQ/blob/077eb0ef691940d764cfd1852bf3981dc812ddbd/main.cpp#L34) and [launch a topology](https://github.com/FairRootGroup/FairMQ/blob/077eb0ef691940d764cfd1852bf3981dc812ddbd/main.cpp#L39) from a C++ program.
+
+## Driving the global state machine
+
+The class [`fair::mq::sdk::Topology`](../fairmq/sdk/Topology.h) adds a FairMQ-specific view on an existing DDS session that is executing a topology of FairMQ devices. One can e.g. [initiate a state transition on all devices in the topology simultaneously](https://github.com/FairRootGroup/FairMQ/blob/077eb0ef691940d764cfd1852bf3981dc812ddbd/main.cpp#L48-L49). This topology transition completes once a topology-wide barrier is passed (all devices completed the transition). This effectively exposes the device state machine as a topology state machine. The implementation is based on remote procedure calls over the [DDS intercom service](http://dds.gsi.de/doc/api-docs/DDS/html/namespacedds_1_1intercom__api.html) between the controller and the DDS plugin shipped with FairMQ (`-DBUILD_DDS_PLUGIN=ON`).
+
+For future versions of the SDK new APIs are planned to inspect and modify the device configurations and also operate only on subsets of a given topology.

+
+A simple topology of two devices - **Sampler** and **Sink**. **Sampler** sends data to **Sink** via the **PUSH-PULL** pattern.
+
+`runSampler.cxx` and `runSink.cxx` configure and run the devices.
+
+The executables take two command line parameters: `--id` and `--channel-config`. The value of `--id` should be a unique identifier and the value for `--channel-config` is the configuration of the communication channel. .
+
+For this and the following example, all the commands needed to start the device are contained in the `fairmq-start-ex-*.sh` script (that can also be used for starting the example).

+1-n-1: Sampler -> Processor(s) -> Sink
+======================================
+
+A simple topology of three devices - **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 communication channels for this example are configured via a JSON file. The matching between device and config entry is done either via id, or the config key. For this example both processor devices share same configuration, and can therefore use same setting from the JSON file. But since their ID still has to be unique, additional command line argument must be used to allow them to share configuration. This parameter is `--config-key`.
+
+In this example the Sampler is configured to **bind** its output and the Sink is configured to also **bind** its input. This allows us run any number of processors with the same configuration, because they all connect to same Sampler and Sink addresses. Furthermore, it allows adding of processors dynamically during run-time. The PUSH and PULL sockets will handle the data distribution to/from the new devices according to their distribution strategies ([Round-robin output for PUSH](http://api.zeromq.org/4-0:zmq-socket#toc14) and [Fair-queued input for PULL](http://api.zeromq.org/4-0:zmq-socket#toc15)).
+
+The Sampler sends out a simple text string (its content configurable with `--text` command line parameter, defaul is "Hello"). Each Processor modifies the string by appending its ID to it and send it to the Sink.
+
+The provided configuration file contains two Processors. To add more Processors, you can either extend the configuration file, or create a separate file only for new processors. Or combine JSON config with `--channel-config` from other examples.

+# FairMQ Examples
+
+Set of FairMQ examples. More examples that combine FairMQ with FairRoot can be found in the [FairRoot repository](https://github.com/FairRootGroup/FairRoot/tree/dev/examples/).
+
+## 1-1
+
+A simple topology of two devices - **Sampler** and **Sink**. **Sampler** sends data to **Sink** with the **PUSH-PULL** pattern.
+
+## 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
+
+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.
+
+## 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.
+
+## 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
+
+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.
+
+## 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.
+
+## 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).
+
+## Request & Reply
+
+This topology contains two devices that communicate with each other via the **REQ-REP** pettern. Bidirectional communication via a single socket.

+Built-in devices
+==========================
+
+This example demonstrates use of generic devices that are provided with FairMQ - BenchmarkSampler, Merger, Multiplier, Proxy, Sink, Splitter. They are all connected in one topology and transfer some dummy buffers generated by the BenchmarkSampler.

+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 contrary to the **PUB-SUB** pattern, this ensures that all receivers are connected and no data is lost, but requires additional sockets.

+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.
+
+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/).
+
+##### 1. The device handles the channel addresses and ports configuration via DDS Plugin.
+
+It is sufficient to provide the `-S "<@FAIRMQ_INSTALL_DIR@/lib" -P dds` (`<` prepends the following path to the default plugin search paths; put in the path which points to the library dir of your FairRoot installation) command line arguments to let the devices be configured dynamically. No code changes in the device are necessary. See the XML topology file for example of using the command line arguments.
+
+##### 2a. Write DDS hosts file that contains a list of worker nodes to run the topology on (When deploying using the SSH plug-in).
+
+We run this example on the local machine for simplicity. The file below defines 3 workers - sampler, processor and sink - with a total of 12 DDS agents (thus able to accept 12 tasks). The parameters for each worker node are:
+ - user-chosen worker ID (must be unique)
+ - a host name with or without a login, in a form: login@host.fqdn (password-less SSH access to these hosts must be possible)
+ - additional SSH params (can be empty)
+ - a remote working directory (most exist on the worker nodes)
+ - number of DDS Agents for this worker
+
+```bash
+@bash_begin@
+#source setup.sh
+@bash_end@
+
+sampler, username@localhost, , /path/to/dds-work-dir/, 1
+processor, username@localhost, , /path/to/dds-work-dir/, 10
+sink, username@localhost, , /path/to/dds-work-dir/, 1
+```
+
+##### 2b. Skip (When deploying using the localhost plug-in).
+
+If you want to deploy on a single host DDS 1.6+ provides a localhost rms plug-in. You do not need a hosts file in that case.
+
+##### 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.
+
+The configuration of the channel connection addresses is done by the DDS plugin via the channel names. The task property names must correspond to the channel names (data1, data2), with binding channels writing the properties and connecting channel reading the properties.
+
+**If you chose step 2b earlier**, then modify the provided `ex-dds-topology.xml` in the top that the following lines read as following:
+```xml
+<declrequirement name="SamplerWorker" type="wnname" value=".*"/>
+<declrequirement name="ProcessorWorker" type="wnname" value=".*"/>
+<declrequirement name="SinkWorker" type="wnname" value=".*"/>
+```
+
+Note that the attributes `value` contain a different value.
+
+##### 4. Start DDS session.
+
+First you need to initialize DDS environment:
+
+```bash
+source DDS_env.sh  # this script is located in the DDS installation directory
+```
+
+The DDS session is started with:
+
+```bash
+dds-session start
+```
+
+##### 5. Submit DDS Agents (configured in the hosts file).
+
+Agents are submitted with:
+```bash
+dds-submit --rms ssh --config ex-dds-hosts.cfg
+```
+The `--rms` option defines a destination resource management system. The `--config` specifies an SSH plug-in resource definition file.
+
+**If you chose step 2b earlier**, run the following command instead:
+
+```bash
+dds-submit --rms localhost -n 12
+```
+
+##### 6. Activate the topology.
+
+```bash
+dds-topology --activate ex-dds-topology.xml
+```
+
+##### 7. Run
+
+After activation, agents will execute the defined tasks on the worker nodes. Output of the tasks will be stored in the directory that was specified in the hosts file (or in the system temporary directory when using the localhost plugin).
+
+##### 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).
+
+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-session.
+
+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
+# get state of sampler
+./fairmq/plugins/DDS/fairmq-dds-command-ui -s 937ffbca-b524-44d8-9898-1d69aedc3751 -c c -p main/Sampler
+# get state of sink
+./fairmq/plugins/DDS/fairmq-dds-command-ui -s 937ffbca-b524-44d8-9898-1d69aedc3751 -c c -p main/Sink
+# get state all processors
+./fairmq/plugins/DDS/fairmq-dds-command-ui -s 937ffbca-b524-44d8-9898-1d69aedc3751 -c c -p main/ProcessorGroup/Processor
+# get state of a specific processor
+./fairmq/plugins/DDS/fairmq-dds-command-ui -s 937ffbca-b524-44d8-9898-1d69aedc3751 -c c -p main/ProcessorGroup/Processor_9
+```
+
+##### 9. Stop DDS session/topology.
+
+The execution of tasks can be stopped with:
+```bash
+dds-topology --stop
+```
+Or by stopping the DDS session:
+```bash
+dds-session stop
+```
+
+For general DDS documentation please refer to [DDS Website](http://dds.gsi.de/).

+Sending Multipart messages
+==========================
+
+A topology of two devices - Sampler and Sink, communicating with PUSH-PULL pattern.
+
+The Sampler sends a multipart message to the Sink, consisting of two message parts - header and body.
+
+Each message part is a regular FairMQMessage. To combine them into a multi-part message use `FairMQParts`. Add messages to `FairMQParts` with `AddPart` method.
+
+All parts are guaranteed to be delivered together. The Receive call in the sink will recive the entire parts structure.
+
+The header contains a simple data structure with one integer. The integer in this structure is used as a stop flag for the sink. As long as its value is 0, the Sink will keep processing the data. Once its value is 1, the data handler method of the Sink will return false, which will exit the RUNNING state of the device.
