This is a follow up to my previous tutorial, if you have not seen it, check it here :

Since I have been asked "what do you do next?". So there here is.
Again, this is how I do it, I'm not saying this is the definitive way of doing it. It works for me, there are probably easier and faster ways to achieve the same thing.
Again, if some things are not clear enough, feel free to leave feedback, I'll update the slides like I did in the previous tutorial
