I'm glad she liked it.
For my mom, I wrote out a step by step guide in a notebook for her to follow. I also put label tags on all the cords.. (USB to computer on one end and round barrel plug to Reader on the other end - same with the wall charger)
I think that if I do it again, I would make screen shots showing arrows pointing to what should be "clicked" in the program to match with the step by step instructions. I would print it out and put it in plastic sleeves in a notebook for her.
It would save a lot of weird hour phone calls to me trying to figure out what she is trying to describe that had "messed" up.
Good Luck.
