No instructions!!!

I'm so confused as to how they ship a door and provide noooooooooo instructions!!!!! I guess my contractors have to read their mind or that both processes or we have to Google and figure this out on our own! This Is a shame after I received the door late

The door has not yet been installed, but it arrived promptly and is ready for the installer. It would help to offer a choice of right and left entry into the shower. I did not think of that because it happens that the picture is the correct entry;however the structure of the shower trim would be better suited with the opposite entry.
