How to replace 2011 Camry front grill
 

Does anybody have steps on how to replace the front grille tho 2011 Camry LE? there seems to be a screw at each end, but there are a lot of tabs, but i've tried putting pressure on the tabs, just don't want to break the bumper. Do I need to remove the bumper first?
Any help would be appreciated

front bumper cover needs remove first , one screw on each side on the top edge where fender meats , all the fender liners clips,screws etc. and all the fog conectors ,and the under covers .
