it starts by making a cross on one face with the edge pieces, then putting the corners into position between the edges. by then the layer should be solved. third, the four edge pieces of the middle layer are solved. at this point the first two layers are solved. fourth, a cross of the opposite color is made on the last layer. fifth, the last layer edges are permutated (swapped around). sixth, the last layer corners are permutated. finally, the last layer corners are oriented.
