Replace Windshield

[begeta50]

Can someone tell me how can I replace the windshiel. My is crack so I need to install a new to my car. I got this from the junk yard, but I have no idea how to replace it.
My car is a 525i 1989.

it may pay to just get it installed by a glass shop, they have the skills for dealing with the trim and getting the glass in the right position, it's glued in and not rubber mounted
