title: documentation for jquery.fn
body: <p>I'm currently learning how to write jquery plugin and I have been told that if I want my plugin to work with jQuery collection in ways similar to the native jquery collection methods, I have to attach it to <code>jQuery.fn</code> object. </p>
  
  <p>Therefore I want to read a bit more about <code>jQuery.fn</code> by reading its documentation page. </p>
  
  <p>Neither google search nor <a href="http://api.jquery.com/?ns0=1&amp;s=%24.fn&amp;go=%3CSPAN%3EGo%3C/SPAN%3E" rel="nofollow noreferrer">search in jquery.com</a> showed up the documentation page for <code>jQuery.fn</code> object. Does the documentation not exist? Or am I not looking at the right place? Or is it because <code>jQuery.fn</code> is internal implementation detail that we shouldn't touch?</p>
