-Of course, feel free to customize the above commands to your needs.
+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)
-if(FairMQ_FOUND)
-  find_package(FairLogger ${FairMQ_FairLogger_VERSION})
-  find_package(Boost ${FairMQ_Boost_VERSION} COMPONENTS ${FairMQ_Boost_COMPONENTS})
-endif()
 ```
 
 When building FairMQ, CMake will print a summary table of all available package 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

+# 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:
+
+```

+                                        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.

+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.
