Info on Metal Halide 400 Watt Lights

I just got some clones and a MH 400 W light. I have two plants and am growing in my spare closet. I've never grown indoors before only outdoors, I need some help on how to set up the lights and everything. How high do I keep the light from the plants and what light cycle should I be using for the baby clones? If you could tell me basically the entire light cycle from start to finish that would help I know nothing right now. Thanks !
