This project is learning how container , Service and ServiceProvider are work together. As my opinion let think there is a box. So I gonna put some toys to that box. You can think the box is container, toys are service .Ok so what about ServiceProvider? Here is answer. If I gonna put toys to that box , I will be a provider. That is how container,service and serviceProvider work. So it is clear ,ServiceProvider are help to put Servics to Container.
I think facades help us to use Class more easily and effectively.
