 FairMQ ships as a CMake package, so in your `CMakeLists.txt` you can discover it like this:

 ```cmake
-find_package(FairMQ)
+find_package(FairCMakeModules 0.2 REQUIRED)
+include(FairFindPackage2)
+find_package2(FairMQ)
+find_package2_implicit_dependencies()
 ```

+The [`FairFindPackage2` module](https://fairrootgroup.github.io/FairCMakeModules/latest/module/FairFindPackage2.html) is part of the [`FairCMakeModules` package](https://fairrootgroup.github.io/FairCMakeModules).
+
 If FairMQ is not installed in system directories, you can hint the installation:

 ```cmake
-set(CMAKE_PREFIX_PATH /path/to/FairMQ_install_prefix ${CMAKE_PREFIX_PATH})
-find_package(FairMQ)
+list(PREPEND CMAKE_PREFIX_PATH /path/to/fairmq_install)
 ```

-`find_package(FairMQ)` will define an imported target `FairMQ::FairMQ`.
-
-In order to succesfully compile and link against the `FairMQ::FairMQ` target, you need to discover its public package dependencies:
-
-```cmake
-find_package(FairMQ)
-if(FairMQ_FOUND)
-  foreach(dep IN LISTS FairMQ_PACKAGE_DEPENDENCIES)
-    if(FairMQ_${dep}_COMPONENTS)
-      find_package(${dep} ${FairMQ_${dep}_VERSION} COMPONENTS ${FairMQ_${dep}_COMPONENTS})
-    else()
-      find_package(${dep} ${FairMQ_${dep}_VERSION})
-    endif()
-  endforeach()
-endif()
-```
-
-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 dds_plugin)

 In some scenarios it is useful to not even instantiate a `FairMQDevice` at all. Please see [this example](../test/protocols/_push_pull_multipart.cxx) for single and multi threaded unit test without a device instance. If you store your transport factories and channels on the heap, pls make sure, you destroy the channels before you destroy the related transport factory for proper shutdown. Channels provide all the `Send/Receive` and `New*Message/New*Poller` APIs provided by the device too.

-TODO Multiple devices in one process.
+## 4.2 Static Analysis
+
+With `-DBUILD_TIDY_TOOL=ON` you can build the `fairmq-tidy` tool that implements static checks on your source code. To use it, enable the generation of a [compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) in your project via `-DCMAKE_EXPORT_COMPILE_COMMANDS=ON` (generates a file `<builddir>/compile_commands.json`):
+
+```
+fairmq-tidy -p <builddir> mysourcefile.cpp
+```
+
+If you find any issue (e.g. false positives) with this tool, please tell us by opening an issue on github.
+
+### 4.2.1 CMake Integration
+
+When discovering a FairMQ installation in your project, explicitely state, that you want one with the `fairmq-tidy` tool included:
+
+```
+find_package(FairMQ COMPONENTS tidy_tool)
+```
+
+Now the CMake module [`FairMQTidy.cmake`](../cmake/FairMQTidy.cmake) is available for inclusion:
+
+```
+include(FairMQTidy)
+```
+
+It provides the CMake function `fairmq_target_tidy()` which attaches appropriate `fairmq-tidy` build rules to each source file contained in the passed library or executable target, e.g. if you have an executable that uses FairMQ:
+
+```
+add_executable(myexe mysource1.cpp mysource2.cpp)
+target_link_libraries(myexe PRIVATE FairMQ::FairMQ)
+fairmq_target_tidy(TARGET myexe)
+```
+
+### 4.2.2 Extra Compiler Arguments
+
+On most Linux distros you are likely to use GCC to compile your projects, so the resulting `compile_commands.json` contains the command-line tuned for GCC which might be missing options needed to successfully invoke the Clang frontend which is used internally by `fairmq-tidy`. In general, you can pass extra `clang` options via the following options:
+
+```
+  --extra-arg=<string>        - Additional argument to append to the compiler command line
+  --extra-arg-before=<string> - Additional argument to prepend to the compiler command line
+```
+
+E.g. if standard headers are not found, you can hint the location like this:
+
+```
+fairmq-top -p <builddir> --extra-arg-before=-I$(clang -print-resource-dir)/include mysourcefile.cpp
+```

+Devices transport data between each other in form of `fair::mq::Message`s. These can be filled with arbitrary content. Message can be initialized in three different ways by calling `NewMessage()`:

 ```cpp
-FairMQMessagePtr NewMessage() const;
+fair::mq::MessagePtr NewMessage() const;
 ```
 **with no parameters**: Initializes an empty message (typically used for receiving).

 ```cpp
-FairMQMessagePtr NewMessage(const size_t size) const;
+fair::mq::MessagePtr NewMessage(const size_t size) const;
 ```
 **given message size**: Initializes message body with a given size. Fill the created contents via buffer pointer.

 ```cpp
 using fairmq_free_fn = void(void* data, void* hint);
-FairMQMessagePtr NewMessage(void* data, const size_t size, fairmq_free_fn* ffn, void* hint = nullptr) const;
+fair::mq::MessagePtr NewMessage(void* data, const size_t size, fairmq_free_fn* ffn, void* hint = nullptr) const;
 ```
 **given existing buffer and a size**: Initialize the message from an existing buffer. In case of ZeroMQ this is a zero-copy operation.

 Additionally, FairMQ provides two more message factories for convenience:
 ```cpp
 template<typename T>
-FairMQMessagePtr NewSimpleMessage(const T& data) const
+fair::mq::MessagePtr NewSimpleMessage(const T& data) const
 ```
 **copy and own**: Copy the `data` argument into the returned message and take ownership (free memory after message is sent). This interface is useful for small, [trivially copyable](http://en.cppreference.com/w/cpp/concept/TriviallyCopyable) data.

 ```cpp
 template<typename T>
-FairMQMessagePtr NewStaticMessage(const T& data) const
+fair::mq::MessagePtr NewStaticMessage(const T& data) const
 ```
 **point to existing memory**: The returned message will point to the `data` argument, but not take ownership (someone else must destruct this variable). Make sure that `data` lives long enough to be successfully sent. This interface is most useful for third party managed, contiguous memory (Be aware of shallow types with internal pointer references! These will not be sent.)

 After queuing a message for sending in FairMQ, the transport takes ownership over the message body and will free it with `free()` after it is no longer used. A callback can be passed to the message object, to be called instead of the destruction with `free()` (for initialization via buffer+size).

 ```cpp
-static void FairMQNoCleanup(void* /*data*/, void* /*obj*/) {}

 ## 2.2 Channel

 A channel represents a communication endpoint in FairMQ. Usage is similar to a traditional Unix network socket. A device usually contains a number of channels that can either listen for incoming connections from channels of other devices or they can connect to other listening channels. Channels are organized by a channel name and a subchannel index.

 ```cpp
-const FairMQChannel& GetChannel(const std::string& channelName, const int index = 0) const;
+const fair::mq::Channel& GetChannel(const std::string& channelName, const int index = 0) const;
 ```

 All subchannels with a common channel name need to be of the same transport type.
