e36 front spoiler dislocated

does anyone know how to take off and put back the front bumper spoiler for a 1997 m3 coupe? i accidently parked too close to the concrete block and in the process of backing off, the front spoiler was dislocated. i can see that it basically popped out of place, all i need to do is to take it out, and put in back in place. however, i don't want to go wondering around my car and take something off, without realizing that i am actually breaking a part or something.

thanks!!
