-## Testing (preliminary)
+## Running the example
 
-To use the tests you also need to clone and build the PySysC-SC repo as sibling of PySysC. It contains the the code and libraries being used in the test.
+To run the example you also need to clone and build the PySysC-SC repo. It contains the the code and libraries being used in the example. This project uses Conan.io as package manager so it should be installed (see down below).
+To deactivate conan and use a SystemC installation just comment out the line `setup_conan()` in CMakeLists.txt and set the environment variable SYSTEMC_HOME.
+
+### Run the router_eample.py
+
+```
+# get the PySysC-SC repo
+git clone --recursive https://git.minres.com/SystemC/PySysC-SC.git
+# build the project libraries as shared libs
+cd PySysC-SC
+mkdir -p build/Debug
+cd build/Debug
+cmake -DCMAKE_BUILD_TYPE=Debug -DBUILD_SHARED_LIBS=ON ../..
+make -j components
+cd ../..
+# now we are ready to run the example
+python3 router_eample.py
+
+```
+
+### Installing conan
+
+```
+# install conan into our virtual environment pysysc-env
+python3 -m pip install conan
+# create the default profile
+conan profile new default --detect
+# add the repo for SystemC packages used in the project
+conan remote add minres https://api.bintray.com/conan/minres/conan-repo
