Tighten the screws:
Thread the other end of the hose up to wherever it will be "discharging" and make sure it's in there real good
Fasten the hose to the machine for extra support. A twist tie works great!
Voila, you're ready to wash some clothes
Per my dad, it's a good idea to turn the water valves off whenever you're not washing clothes. That way you'll never come home to a flood.
