Your pineapple should be very ripe, to check this, you should be able to pull out one of the central leaves easily.
2: Start with top: cut about 1 cm or ½ inch beneath the leaves.
3: Then the bottom, remove 1 cm or ½ inch here too.
4: Stand the pineapple up, and cut vertically in strips to remove all the skin.
5: Go over the outside again to cut off any remaining "eyes". Pineapple should now be completely yellow.
6: Cut pineapple into quarters vertically.
7: Lay each piece flat, cut out the hard fibrous core. Also remove any brown over-ripe parts.
8: Then cut quarters as required for your recipe, here in medium size pieces.
9: Finally, squeeze all the pieces of skin or trimmings of flesh in your hands to extract the juice that you can drink or use in a recipe or a cocktail.
Remarks
This method applies to a Victoria Pineapple (small, but incredably tasty, especially if they come from Reunion), but of course it's the same for other kinds of pineapple.
