 ## Implementations
 
-Each algorithm has C and Python implementations.
+Each algorithm has Rust and Python implementations.
 
-On a typical CPython install the C implementation will be used. The Python versions
-are available for PyPy and systems where compiling the CPython extension is not
-possible.
+The Rust implementations are used by default. The Python
+implementations are a remnant of an early version of 
+the library and will probably be removed in 1.0.
 
 To explicitly use a specific implementation, refer to the appropriate module::
 
 ``` python
-  import jellyfish._jellyfish as pyjellyfish
-  import jellyfish.cjellyfish as cjellyfish
