You have to find where it's leaking from. From your description it leaked out almost immediately so look for a split or loose radiator hose. Check all the hoses, check the radiator petcock. Then start looking at things like water pump gasket, thermostat housing, engine block freeze plugs. A cooling system pressure test can find a leak pretty quick if a visual inspection doesn't reveal one. DO NOT drive the car with it low on coolant, an overheating engine will die a premature death. After replacing any failed cooling system parts, top off coolant and be sure to bleed air from system, it may take more than one attempt to get all the air out.
