+# Minimum Desktop Runtime
+
+We provide some generic output which will also work on Linux, Windows and OS/X
+The cmake is downloading all dependencies and builds an executable from the sketch.
+
+This example is not using the Arduino-Emulator!
+
+You just need to provide an Arduino Sketch as cpp file. In our example we use an example setup that can be compiled both in Arduin and with cmake: 
+
+- the sketch is provided as ino file
+- you must not include Arduino.h since this is not available
+
+To build the example execute
+
+```
+mkdir build
+cd build
+cmake ..
+make
+```
