GAMBIT to SATURNE

I am knew to code_saturne and Salome. I am a Gambit Fluent user. Does anyone know how to get a gambit file into code saturne. In the documentation there is no step by step process of how to do this. Can someone shed some light on this. I have been able to export a neu file and import this in. However there is no boundary conditions setup so the geometry is useless when imported.
