 ## Writing your own Middleware Generator
 see [TUTORIAL_ADD_MIDDLEWARE.md](https://git.rwth-aachen.de/monticore/EmbeddedMontiArc/generators/EMAM2Middleware/blob/master/TUTORIAL_ADD_MIDDLEWARE.md)
 
+## Dependencies needed to compile the generated projects
+### CMake
+CMake and Make are required to compile the generated projects.
+
+Usage: Navigate to your build directory and run `cmake $srcPath`, where srcPath is the path to the generated project to be compiled. Next run `make` 
+
+### Cpp
+Armadillo version 8 or higher.
+The version used in EMAStudio can be downloaded from:
+* [Windows](https://github.com/EmbeddedMontiArc/EMAStudioBuilder/releases/download/libraries/armadillo-8.200.2.zip)
+* [Linux](https://rwth-aachen.sciebo.de/s/igDWzLpdO5zYHBj/download?path=%2Fubuntu%2F18.06.20-armadillo-linux&files=armadillo-8.500.1-linux.zip)
+
+WARNING: Both linked versions contain a copy of the file `armadillo` called `armadillo.h`, which is not contained in standard armadillo distributions.
+It is required by the code generated by EMAM2Cpp.
+
+The environment variable `Armadillo_HOME` needs to be set to the base directory of your armadillo installation.
+
+### Roscpp
+Only for generated projects that contain a ROS adapter(e.g. -g=cpp,roscpp).
+ROS Kinetic currently only supports Linux and the installation is described [here](http://wiki.ros.org/kinetic/Installation/Ubuntu).
