  * **Warning** pygments is relatively slow and our integration isn't
 as optimized as it could be. Expect much longer build times when using server side highlighting.
  * Languages available depends on your pygments installation.
- * While pygments supports a few different output formats and options we currently
-only support output=html, style=monokai, noclasses=true, and encoding=utf-8.
  * Styles are inline in order to be supported in syndicated content when references
 to style sheets are not carried over.
