I have seen lots of people getting confused and asking about paperwork in the forum times and again. There is ample documentation available on the topic, still people get into small issue.
In last couple of weeks, I recd calls from some members about documentation aspect of application. I tried to find out in my old links, most of those do not work. So this time I am providing hyperlink and content of the hyperlink, so that even if hyperlink is gone, we will still have something to refer to.
