1. Add the directory with the Siren executables to your path.
2. Set the environment variable SIRENHOME to the directory containing Siren. Siren will look there for a file called Siren.rib, which should contain default rendering options and attributes.
3. Set the environment variable SHADECH to a path containing the directories the shading compiler should search for header files.
If this is your first time to use Siren, you are encouraged to read the documentation and to work through the introductory tutorial, Command Line Rendering with Siren
