Blender import problem

When I looked up how to bring my blender models into unity it said to simply put it into assets folder however when I do that I just get black outline in the assets area and nothing shows up when I bring it into the scene

 

Make sure your model is at the origin in Blender and you've applied Location, Rotation and Scale to reset their offsets to zero. Your model may be there in the scene, but the mesh itself could be way off the screen somewhere.
