     This fragment is a Markdown_ preprocessor that renders source code
     to HTML via Pygments.  To use it, invoke Markdown like so::
 
-        from markdown import Markdown
+        import markdown
 
-        md = Markdown()
-        md.textPreprocessors.insert(0, CodeBlockPreprocessor())
-        html = md.convert(someText)
-
-    markdown is then a callable that can be passed to the context of
-    a template and used in that template, for example.
+        html = markdown.markdown(someText, extensions=[CodeBlockExtension()])
 
     This uses CSS classes by default, so use
     ``pygmentize -S <some style> -f html > pygments.css``
