+Converts URLs in text into clickable links.
 
-Note that if ``urlize`` is applied to text that already contains HTML markup,

+Works on links beginning with ``http://``, ``https://``, or ``www.`` and 
+ending with ``.org``, ``.net`` or ``.com``. Links can have trailing punctuation
+(periods, commas, close-parens) and leading punctuation (opening parens) and
+``urlize`` will still do the right thing.
+
+Links generated by ``urlize`` have a ``rel="nofollow"`` attribute added
+to them.
 
 For example::
 
     {{ value|urlize }}
 
 If ``value`` is ``"Check out www.djangoproject.com"``, the output will be
-``"Check out <a
-href="http://www.djangoproject.com">www.djangoproject.com</a>"``.
+``"Check out <a href="http://www.djangoproject.com"
+rel="nofollow">www.djangoproject.com</a>"``.
+
+The ``urlize`` filter also takes an optional parameter ``autoescape``. If
+``autoescape`` is ``True``, the link text and URLs will be escaped using
+Django's built-in :tfilter:`escape` filter. The default value for
+``autoescape`` is ``True``.
+
+.. note::
+
+    If ``urlize`` is applied to text that already contains HTML markup,
+    things won't work as expected. Apply this filter only to plain text.
