Orient last layer
Almost there. Here you have to learn 57 algorithms to orient the last layer (put all yellow pieces on top).
This is simply learning a lot of algorithms. If you are just beginning it's better to learn the PLL's first and do the OLL in 2 steps! OLL in 2 steps: learn 2 algorithms to orient the edges, and learn the 7 algorithms to orient the corners where all edges are already oriented.
