I'm assuming that you're talking about the letters that go with PLLs (H, U, Z, A, E, G, V, F, T, Y, N, R, J, L). In that case, I think it's on the wiki. Let me fetch a link.
The pictures are a birds-eye view of the cube when the top face is oriented (OLL done) but the PLL still needs doing. There is one colour of arrows showing how the edges need to be moved, and one colour of arrows showing how the corners need to be moved. However, sometimes only edges will need switching, or only corners will need switching.
