 Speed Extensions
 ----------------
 
-.. versionadded:: 0.8.5
-
-Tablib is partially dependent on the **simplejson**, and **xlwt** modules. To reduce installation issues, fully integrated versions of all required libraries are included in Tablib.
-
-If you're using Python 2.5, you should also install the **simplejson** module (pip will do this for you). If you're using Python 2.6+, the built-in **json** module is already optimized and in use. ::
-
-    $ pip install simplejson
+You can gain some speed improvement by optionally installing the ujson_ library.
+Tablib will fallback to the standard `json` module if it doesn't find ``ujson``.
