Why isn't there any helpful documentation about Simulink Model Deployment?

I have been searching about deploying Simulink models but there is not any documentation or video about this.

Problems are getting deeper and nobody cares, at all.

• It is almost impossible to find out how to use a Simulink Generated Code. There is no example.
• Matlab R2013a is not compatible with Visual Studio 2013. Thus I always get the error of "No compatible Visual C++ Compiler found" error.
• (Nobody replies my contact trials from Matlab Support)

The more I go deeper in it the more complicated it gets. Problems and questions get multiplied.
