 The core of FairMQ provides an abstract asynchronous message passing API with scalability protocols

 ## Usage
 
 FairMQ ships as a CMake package, so in your `CMakeLists.txt` you can discover it like this:
 
 ```cmake
-find_package(FairCMakeModules 0.2 REQUIRED)
+find_package(FairCMakeModules 1.0 REQUIRED)
 include(FairFindPackage2)
 find_package2(FairMQ)
 find_package2_implicit_dependencies()
@@ -68,31 +94,19 @@ If FairMQ is not installed in system directories, you can hint the installation:
 list(PREPEND CMAKE_PREFIX_PATH /path/to/fairmq_install)

-Optionally, you can require certain FairMQ package components and a minimum version:
-
-```cmake
-find_package(FairMQ 1.4.0 COMPONENTS dds_plugin)
-```
-
-When building FairMQ, CMake will print a summary table of all available package components.

 ## 7.3 Provided Plugins
 
-### 7.3.1 DDS
+### 7.3.1 PMIx
 
-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.
+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 experimental plugin has been last released in v1.4.56 and is removed in v1.5+. For now there are no plans to pick up development of it again.
-
-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).

-# 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 topology of three devices - **Sampler**, **Sink** and **Broadcaster**. The Sampler sends data to the Sink via the PUSH-PULL pattern. The Broadcaster device sends a message to both Sampler and Sink containing a string "OK" every second. The Broadcaster sends the message via PUB pattern. Both Sampler and Sink, besides doing their PUSH-PULL job, listen via SUB to the Broadcaster.
