Remove the covers of the double-sided tape and lay the bezel over the display assembly. First lay down the bottom edge between the hinges which will help you to better centre the bezel and then make it turn down.

Afterwards, starting from the middle of the bottom edge and going towards the short edges, snap all the tabs of the bezel back into position. Finish the reassembly at the webcam and press a little over the areas where you laid the adhesive.
