Install brew on Mac

I love Unix. The most beautiful things in Unix, especially on MacOS is console. Maybe most people thought Mac is the most beautiful OS in the world. Well, perhaps. I'm not apple fan boy. But I'm Unix fan boy.  :)

Even MacOS is my primary companion, I still need more. Most of my time spend on console. Not MacOS fancy UI. I need more power on console. Therefore, brew came to help.
