+This module implements SHA-3 (also known as Keccak) with a

+The module is written as a Python C extension on top of the reference

 ## Caveats
 
-While Keccak is tweakable, can hash on a bit level etc, this module is
-not. It works on byte arrays only. It also works with the select block
-sizes only.
+While reference Keccak is tweakable and can hash bit strings, this
+module has the same API as the python `hashlib` module and work on
+bytes only.
+
+The current implementation most likely has a bug or two. There could
+be endian-ness issues as well.
