Personal notes on solving 3x3 cube.

Edit: Don't do this often enough, additional notes for the third layer

third layer: F R U R' U' F'

Repeat this three time if only yellow center is valid.

Repeat this twice if yellow layer is a small L away from front side.

Repeat this once if yellow is a horizontal line left-right.

This should result in a yellow-cross on the top-surface only!

This rotates the three edges away from the front face counter-clockwise. Do until the wall edges aligns with the cross.

The following rotates the corner pieces in the rear triangular surface. Rotate until the top corner pieces are aligned.

Flip the corner pieces closest to you Front/Right (re-orient), do this and always keep the corner you want to solve F/R. rotate the top surface. Keep doing this until the cube is solved!

My notes, third layer was an older algorithm, which now I don't really recall to follow anymore (at least not how to solve the yellow cross)
