How to export ready rig to source engine.

I have made a model (rig too) and i want to know how i can export skeleton to source engine.
I’m using blender to model,rig and animate my characters, and i’d wanted to see how the model with behave in source engine world.
Any help will be usefull.
EDIT: everytime i want to export rig, it says “No actions or NLA” and its the reason why i cant export. (or its something else).
