+# Simulink RPP Target and Library #
+#####################################
-./rpp/rpp should be on the MATLAB path.
+This is the repository of the Simulink target.
+
+To work with the Simulink target you also need the RPP Library, which
+can be obtained from another repository with the following command:
+
+ git submodule update --init
+
+This repository is structured as follows:
+
+ - doc/ This directory hold documentation created for this project.
+
+ - refs/ Hold oficial reference documentation for CPU, chips,
+ languages, compiler, etc. This files are constantly
+ referenced within the source code files in this repository.
+
+ - rpp/blocks Hold the Simulink block library for the RPP Target.
+ C MEX S-Functions and TLC files can be found here.
+ See dedicated README.txt file for more information.
+
+ - rpp/demos Simulink demos that uses the RPP target and block library.
+ See dedicated README.txt file for more information.
+
+ - rpp/lib RPP Library and API. See dedicated README.txt file for more
+ information.
+
+ - rpp/rpp Simulink RPP Target for code generation. See dedicated
+ README.txt file for more information.
