I built my first missile defense system, but I can't figure out how to use it. I power it with a medium solar panel and battery so it has power 24-7, but it says it has 0/5 capacity, with no button to load it. It has a box on top saying rocket fuel, but I can't figure out a way to get rocket fuel to load inside. It's very confusing. Is it in one of the tutorials? If not, can you put something into the FAQ about how to use it?
