The Square-1 is a interesting puzzle- the concepts of other puzzles can be applied to it, however, it is unique in that corners and edges are indistinguishable to the puzzle's inner mechanism- meaning corners can be swapped with edges and therefore the puzzle can change shape. The puzzle is much easier to work with when it is in the shape of a cube so generally the first step is to somehow (there are several methods) get the pieces arranged so that the puzzle is cubic. Then, the pieces are separated into their correct layers, and permuted. Note that there is no possible incorrect orientation for pieces, since the middle layer can only rotate through 180 degrees at a time (many talks about separation as "orientation").
