+Attribute Lists
+===============
+
+Summary
+-------
+
+An extension to Python-Markdown that adds a syntax to define attributes on
+the various HTML elements in markdown's output.
+
+This extension is included in the standard Markdown library.
+
+Syntax
+------
+
+The basic syntax was inspired by [Maruku][]'s Attribute List feature.
+
+[Maruku]: http://maruku.rubyforge.org/proposal.html#attribute_lists
+
+### The List ###
+
+An example attribute list might look like this:
+
+    {: #someid .someclass somekey='some values' }
+
+A word which starts with a hash `#` will set the id of an element.
+
+A word which starts with a dot `.` will add to the list of classes assigned to
+an element.
+
+A key/value pair will assign that pair to the element.
+
+Be aware that while the dot syntax will add to a class, using key/value pairs
+will always override the previously defined attribute. Consider the following:
+
+    {: #id1 .class1 id=id2 class="class2 class3" .class4 }
+
+The above example would result in the following attributes being defined:
+
+    id="id2 class="class2 class3 class4"
+
+### Block Level ###
+
+To define attributes for a block level element, the attribute list should
+be defined on the last line of the block by itself.
+
+    This is a paragraph.
+    {: #an_id .a_class }
+
+The above results in the following output:
+
+    <p id="an_id" class="a_class">This is a paragraph.</p>
+
+The one exception is headers, as they are only ever allowed on one line.
+
+    A setext style header {: #setext}
+    =================================
+
+    ### A hash style header ### {: #hash }
+
+The above results in the following output:
+
+    <h1 id="setext">A setext style header</h1>
+    <h3 id="hash">A hash style header</h3>
+
+### Inline ###
+
+To define attributes on inline elements, the attribute list should be defined 
+immediately after the inline element with no whitespace.
+
+    [link](http://example.com){: class="foo bar" title="Some title! }
+
+The above results in the following output:
+
+    <p><a href="http://example.com" class="foo bar" title="Some title!">link</a></p>
