Summary

Unscrew the corner screws holding the metal plate to the heating surface.
Place the Glass Bed Holders under the heating surface with the screw going through the metal plate and into your bed holders
Place the nut and tighten the screw.
There is room for movement on the holder so you can adjust the holder to match your glass bed size.
If you just bought your glass bed use 2-3 chip bag clips to hold your bed down while these print.

(dont mind the fingerprints I put on the bed while adding the holders)
