This protection, you arrive in a well-designed box. This protection does not come with a French assembly instructions. In the box there is an isopropyl alcohol pad and a small cloth, and a brown film to remove dust. Clean your hands well and the laying surface and remove your phone battery with a liquid glass. Make sure your phone with important insights that there is no dust, put the window side A (side glue) button near the bottom and let this land without support, the window will stick alone; let the second film and scrub with a stiff card on this film, once you no longer remove the last bubble film. Very good video on Youtube installation to help you. The result is good, except I think this glass reflects too the outside light of the phone.
