1. First of all we have to solve the white edge pieces in the bottom. This seems to be the easiest but it's really hard if you want to do it right. You should be able to determine all the rotations needed to complete the white cross after inspecting the cube, and you'll succeed only if you foresee 7 steps.
2. When the cross is done we solve the first two layers (F2L) in one step using a technique to pair the white corner and second layer edge pieces. We are talking about four corner blocks which usually require 4x7 steps.
3. Orienting the last layer (OLL) of the Rubik's Cube is the step in which we solve the yellow face without matching the side colours. We are going to position them in the next step. Learn all the 57 algorithms to complete this step.
4. Permutate the last layer (PLL) to finish the solution of your cube. There are 21 algorithms to memorize.
