jQuery license details

Hi!

A few weeks ago I already postet a comment into this forum to inform about the use of jQuery in commercial projects. I got a reply by a user in this forum, but there is still a question, I don't have an answer to. So maybe an official member of jQuery could reply to my question.

In MIT-License it says that the "copyright notice and the permission should be included in all copies or substantial portions of the software".

So if I create a website and sell it to my customer - what do I have to do to avoid violating any copyright?

In my main html document I refer to the jQuery source file (jquery-1.7.2.js) by this tag:
<script type="text/javascript" src="jquery-1.7.2.js"></script> and I did not edit the source file, so the copyright header is left intact.

Do I additionally have to add any copyright notice to the files of my website which I created? For example to the main html document or my javascript file in which I use jQuery commands?

Sorry for asking again on this topic but it is hard to get any official answer by a jQuery member on my questions. I just want to do everything in a legal way!!!

Thank you!
