+- Major update for version handling, using `git describe` to fetch version information with git.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/601
+  - Place `Version` class outside of `fsfw` namespace. It is generic
+  - Add helper functions provided by [`cmake-modules`](https://github.com/bilke/cmake-modules)
+    manually now. Those should not change too often and only a small subset is needed
+  - Separate folder for easier update and for distinction
+  - LICENSE file included
+  - use `int` for version numbers to allow unset or uninitialized version
+  - Initialize Version object with numbers set to -1
+  - Instead of hardcoding the git hash, it is now retrieved from git
+  - `Version` now allows specifying additional version information like the git SHA1 hash and the
+    versions since the last tag
+  - Additional information is set to the last part of the git describe output for `FSFW_VERSION` now.
+  - Version still need to be hand-updated if the FSFW is not included as a submodule for now.
+- IPC Message Queue Handling: Allow passing an optional `MqArgs` argument into the MessageQueue

+## Prerequisites
+
+The Embedded Template Library (etl) is a dependency of the FSFW which is automatically
+installed and provided by the build system unless the correction version was installed.
+The current recommended version can be found inside the fsfw `CMakeLists.txt` file or by using
+`ccmake` and looking up the `FSFW_ETL_LIB_MAJOR_VERSION` variable.

+You can install the ETL library like this. On Linux, it might be necessary to add `sudo` before

+
+```cpp
+git clone https://github.com/ETLCPP/etl
+cd etl
+git checkout <currentRecommendedVersion>
+mkdir build && cd build
+cmake ..
+cmake --install .

+You can install the Catch2 library, which prevents the build system to avoid re-downloading

+# 2012-01-31, Lars Bilke
+# - Enable Code Coverage
+#
+# 2013-09-17, Joakim Söderberg
+# - Added support for Clang.
+# - Some additional usage instructions.
+#
+# 2016-02-03, Lars Bilke
+# - Refactored functions to use named parameters
+#
+# 2017-06-02, Lars Bilke
+# - Merged with modified version from github.com/ufz/ogs
+#
+# 2019-05-06, Anatolii Kurotych
+# - Remove unnecessary --coverage flag
+#
+# 2019-12-13, FeRD (Frank Dana)
+# - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor
+#   of tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments.
+# - CMake 3.4+: All excludes can be specified relative to BASE_DIRECTORY
+# - All setup functions: accept BASE_DIRECTORY, EXCLUDE list
+# - Set lcov basedir with -b argument
+# - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be
+#   overridden with NO_DEMANGLE option in setup_target_for_coverage_lcovr().)
+# - Delete output dir, .info file on 'make clean'
+# - Remove Python detection, since version mismatches will break gcovr
+# - Minor cleanup (lowercase function names, update examples...)
+#
+# 2019-12-19, FeRD (Frank Dana)
+# - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
+#
+# 2020-01-19, Bob Apthorpe
+# - Added gfortran support
+#
+# 2020-02-17, FeRD (Frank Dana)
+# - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters
+#   in EXCLUDEs, and remove manual escaping from gcovr targets
+#
+# 2021-01-19, Robin Mueller
+# - Add CODE_COVERAGE_VERBOSE option which will allow to print out commands which are run
+# - Added the option for users to set the GCOVR_ADDITIONAL_ARGS variable to supply additional
+#   flags to the gcovr command
+#
+# 2020-05-04, Mihchael Davis
+#     - Add -fprofile-abs-path to make gcno files contain absolute paths
+#     - Fix BASE_DIRECTORY not working when defined
+#     - Change BYPRODUCT from folder to index.html to stop ninja from complaining about double defines
+#
+# 2021-05-10, Martin Stump
+#     - Check if the generator is multi-config before warning about non-Debug builds
+#
+# 2022-02-22, Marko Wehle
+#     - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output respectively.
+#       This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS, e.g. GCOVR_ADDITIONAL_ARGS "--txt".
+#
+# USAGE:
+#
+# 1. Copy this file into your cmake modules path.
+#
+# 2. Add the following line to your CMakeLists.txt (best inside an if-condition
+#    using a CMake option() to enable it just optionally):
+#      include(CodeCoverage)
+#
+# 3. Append necessary compiler flags for all supported source files:
+#      append_coverage_compiler_flags()
+#    Or for specific target:
+#      append_coverage_compiler_flags_to_target(YOUR_TARGET_NAME)
+#
+# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
+#
+# 4. If you need to exclude additional directories from the report, specify them
+#    using full paths in the COVERAGE_EXCLUDES variable before calling
+#    setup_target_for_coverage_*().
+#    Example:
+#      set(COVERAGE_EXCLUDES
+#          '${PROJECT_SOURCE_DIR}/src/dir1/*'
+#          '/path/to/my/src/dir2/*')
+#    Or, use the EXCLUDE argument to setup_target_for_coverage_*().
+#    Example:
+#      setup_target_for_coverage_lcov(
+#          NAME coverage
+#          EXECUTABLE testrunner
+#          EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*" "/path/to/my/src/dir2/*")
+#
+# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set
+#     relative to the BASE_DIRECTORY (default: PROJECT_SOURCE_DIR)
+#     Example:
+#       set(COVERAGE_EXCLUDES "dir1/*")
+#       setup_target_for_coverage_gcovr_html(
+#           NAME coverage
+#           EXECUTABLE testrunner
+#           BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src"
+#           EXCLUDE "dir2/*")
+#
+# 5. Use the functions described below to create a custom make target which
+#    runs your test executable and produces a code coverage report.
+#
+# 6. Build a Debug build:
+#      cmake -DCMAKE_BUILD_TYPE=Debug ..
+#      make
+#      make my_coverage_target
+#

 information about the possible options.
 
+Prerequisites
+-------------------
+
+The Embedded Template Library (etl) is a dependency of the FSFW which is automatically
+installed and provided by the build system unless the correction version was installed.
+The current recommended version can be found inside the fsfw ``CMakeLists.txt`` file or by using
+``ccmake`` and looking up the ``FSFW_ETL_LIB_MAJOR_VERSION`` variable.
+
+You can install the ETL library like this. On Linux, it might be necessary to add ``sudo`` before
+the install call:
+
+.. code-block:: console
+
+   git clone https://github.com/ETLCPP/etl
+   cd etl
+   git checkout <currentRecommendedVersion>
+   mkdir build && cd build
+   cmake ..
+   cmake --install .
+
+It is recommended to install ``20.27.2`` or newer for the package version handling of
+ETL to work.
+
 Adding the library
 -------------------
 
@@ -60,6 +83,20 @@ The FSFW also has unittests which use the `Catch2 library`_.
 These are built by setting the CMake option ``FSFW_BUILD_UNITTESTS`` to ``ON`` or `TRUE`
 from your project `CMakeLists.txt` file or from the command line.
 
+You can install the Catch2 library, which prevents the build system to avoid re-downloading
+the dependency if the unit tests are completely rebuilt. The current recommended version
+can be found inside the fsfw ``CMakeLists.txt`` file or by using ``ccmake`` and looking up
+the ``FSFW_CATCH2_LIB_VERSION`` variable.
+
+.. code-block:: console
+
+   git clone https://github.com/catchorg/Catch2.git
+   cd Catch2
+   git checkout <currentRecommendedVersion>
+   cmake -Bbuild -H. -DBUILD_TESTING=OFF
+   sudo cmake --build build/ --target install
+
+
 The fsfw-tests binary will be built as part of the static library and dropped alongside it.
 If the unittests are built, the library and the tests will be built with coverage information by
 default. This can be disabled by setting the `FSFW_TESTS_COV_GEN` option to `OFF` or `FALSE`.
