+This repository contains dependencies needed by the simulink connector plugin (https://git.qt.io/mbadri/simulinkconnector). Dependencies are provided by MathWorks (mathworks.com).
+
+The package is composed of three components:
+1) Simulink Qt Block Library (QtBlocksetPSP-R2019b_v2.1.3_win64-Install.exe)
+2) Qt plugin (simulinkplugin) for connectivity to the Simulink environment using C++
+3) QML Extension plugin (simulinkqmlplugin) which allows the simulinkplugin to be used in QML directly.
