You will need to remove the rubber feet and strip at the edge.

Keep in mind the edge strip is difficult to work with, as you can see I accidentally ripped mine.

You will want to use a spudger or small slotted screwdriver to pull up the strip as you go so you don't do as I did.

Once you've removed the strip you'll see a couple screws on either side, that is not all of them, you need to remove the plastic strip that is below the rubber strip as well, you will then find a few additional screws to remove.
