Pretty simple.

Wash and dry prep.

Agitate the primer with a brush or sponge tip applicator for 20
seconds over the entire preparation (add more primer as needed to
keep quite wet).

Dry (do not wash) with a gentle air stream.

Place bond over entire prep and let set for 10 seconds.  Thin with
air, or sponge off extra bonding resin.

Cure 5 seconds with high output halogen light.

Continue with regular filling technique.

Does not bond well to *uncut* enamel, so you have to use a diamond, bur,
AA, or laser on anything you want to bond to beyond the preparation.

Best wishes,
