Cubology step 2: Solve first layer corners

1: Find a target cubie (a corner cubie with a facelet the color of the bottom face)

2: If it is in the top layer, rotate the top layer until it is above the target position (The target position is in between the three middles of the same color as the target cubie's facelets) and use one of these to solve it:

3:If it is in the right place, but flipped, use one of these:

4: If it is in the bottom layer, but in the wrong place use one of the step 2 algorithms to knock it out.

5: Repeat steps 1 thru 4 until all the first layer corners are solved.
