Can you use it on grass?

would we set it up differently if it was set up on grass? could we even use it on grass, would the first small pole be hammered to the gras or could it be left as it is and not in the grass and just tighten the strings to make the tension tighter causing the poles to stand upright and sturdy? would this work?

Does the lines , come with the net?
