+Hash Functions
+==============
+
+- :func:`murmurhash3_32` provides a python wrapper for the
+  `MurmurHash3_x86_32` C++ non cryptographic hash function. This hash
+  function is suitable for implementing lookup tables, Bloom filters,
+  Count Min Sketch, feature hashing and implicitly defined sparse
+  random projections.
+
+  The ``sklearn.utils.murmurhash`` module can also be "cimported" from
+  other cython modules so as to benefit from the high performance of
+  MurmurHash while skipping the overhead of the Python interpreter.
