In this step you solve the bottom edges, and finish the cube. First what you want to do is rotate the cube so that the bottom becomes the top. Then you want to flip the remaining edges so the top is one solid color. There is two different manuvers you have to use to do this.

To flip the remaining edges match your cube with the cube below then fallow the move sequence.

After you flip the remaining edges, you now have to solve the cube from there using the sequence below. It rotates the 3 remaining edges counter clock wise. So if you have one edge that is in the correct spot alread, make that your face and perform the manuver below, if there is no correct edge, chosse any face and do the manuver below. (you might have to perform this manuver more than once)
