Confusing wording in mini12864 instructions

[arkeet]

A user recently had a problem getting the display working, misunderstanding the header flip image and thinking "yes" meant to flip one connector, and "no" meant to not flip the other. Suggestion:

• Change the words the image to say "correct" and "wrong" or something similar.
• Change step 2 to say something like "Rotate both connector housings 180 degrees and insert back onto pins."

I'd suggest also changing the first sentence from NOTE: The connector housing only need to be reversed... to NOTE: The 2 connector housings only need to be reversed...
