Step two: the first layer

In this step you need to pay attention to the other two colors that stand by the white corner piece and the sides of identical colors. The color of the central piece in a face defines the color of that face and the position of these colors is unchangeable!

If the white corner piece is on the top layer (and if it is necessary), we drag it to the appropriate angle of the matched colors and (by turning the whole cube) we prepare the starting position.
The starting position is: upper front right corner!

There are three possibilities for positioning the white piece: on the right, on the front face, and on the top. According to that, we must apply the appropriate moves which will be now shown.

White on the right

White on the front

White on the top

White on the bottom

These same algorithms are applied to the white corner pieces when they are in the bottom layer, with the aim to drag them to the top layer. We are talking about the pieces the starting position of which is at the wrong place, and which, therefore, need to be dragged out and put on their correct position.
Advice: always start dragging out the pieces by putting the right piece on that position, with that action you will save at least three rotations, i.e. your Rubik's Cube will be solved faster. The following video illustrates this action:
