Right position

Hi fellows,
I know there's a file with a description and a picture about the right position for writing, but I cannot read it, because it's too small.
Perhaps, time ago, this subject was already talked... so, can anyone give me some instructions to follow, please?
I mean, about how to grab the pen, how to put the arm, the paper, etc.
