 The aim of this project is to rework the original [Traffic Flow Dynamics Model](https://github.com/Grufoony/TrafficFlowDynamicsModel).
 This rework consists of a full code rewriting, in order to implement more features (like *intersections*) and get advantage from the latest C++ updates.
 
 ## Requirements
 
-The project only requires `C++20` or greater and `cmake`.
+The project requires `C++20` or greater, `cmake` and `tbb`.
+To install requirements on Ubuntu:
+```shell
+sudo apt install libtbb-dev cmake
+```
+To install requirements on MacOS:
+```shell
+brew install tbb cmake
