To do first lesson, place your left hand side four fingers on Asdf ;
On A: Smallest finger
On s: Finger next to smallest finger
On d: middle finger
On F: Finer before thumb
G: the finger which you use to press f, will be used to type G as well.
On f you will see a little bump, which helps you to identify F key, without looking at keyboard.

On ; : Smallest finger of right hand
On L: Finger next to smallest finger
On K: Middle finger of right hand
On J : Figner next to thumb
