+When considering contributing code, it might be good to know that build configurations for Azure pipelines are present in the repository and that there is a test suite built using a simple testing framework and CTest that can be built locally if desired.
 To build it, set the cmake variable `BUILD_TESTING` to on when configuring, e.g.:
 
     $ cd build
     $ cmake -DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTING=ON ..
     $ cmake --build .
     $ ctest
 
-Such a build requires the presence of [CUnit](http://cunit.sourceforge.net/).
-You can install this yourself, or you can choose to instead rely on the [Conan](https://conan.io) packaging system that the CI build infrastructure also uses.
-In that case, install Conan and do:
-
-    $ conan install .. --build missing
-
-in the build directory prior to running cmake.
-
-For Windows, depending on the generator, you might also need to add switches to select the architecture and build type, e.g., `conan install -s arch=x86_64 -s build_type=Debug ..`
-This will automatically download and/or build CUnit (and, at the moment, OpenSSL).

 ## Documentation
 
 The [documentation](https://cyclonedds.io/docs) is still rather limited and some parts of it are still only available in the form of text files in the `docs` directory.
