 Identity
 ^^^^^^^^
 
-Wrapper driver.
+Wrapper driver. The identity driver is a simple skeleton that passes through
+all of its :ref:`Context` and :ref:`Screen` methods to an underlying Context
+and Screen, and as such, it is an excellent starting point for new drivers.
 
 LLVM Softpipe
 ^^^^^^^^^^^^^
 
-nVidia nv30
-^^^^^^^^^^^
+A version of :ref:`softpipe` that uses the Low-Level Virtual Machine to
+dynamically generate optimized rasterizing pipelines.
