This is a quick guideline to get rid of reading long and boring documentation and give you very basic information about a screen.

In my childhood, my uncle has shown me how to see the cloud in a close look and I understand that one can draw some elements of the Earth in the sky-canvas if he/she wants to. After that the cloud becomes closer to me and It teaches me one thing that, a deeper-look to something will give you some clues to draw your imagination. You can able to see that one which you have build-up in your mind.
Years past, I have started my career as a software engineer and has been looking for passion in my coding and development which I should be to enjoy my profession and has started asking myself- 'am I doing any engineering here?!' Is my code becoming that thing which I have designed in my mind? So to find that answer I have tried that old solution here... I have decided to come closer to my code and start analyzing them. And it is really working for me and at least it gives me the confidence that I can build something that I really want to. I can draw my thinking there through my code and can build-up my vision that I have designed in my mind. It also helps me to think out of the box, solve each problems by making blocks and make me careful on each steps.
