First of all, I have to apologize for writing this way to you.
I admit to being fustrated, but my fustration was not with you. it
was with myself, because I don't understand exactly what it is that
you'd like me to put in the comment.

I know this situation will happen again in the future because we
all have different conceptions of what necessary documentation is.
I will try to say it openly when I don't understand, so that you
can help me (please :).

Do you still think a comment should be added? If yes, is the comment
I suggested a step in the right direction?
