-``cryptography`` has three different layers:
-
-* ``cryptography``: This package contains higher level recipes, for example
-  "encrypt and then MAC". This is implemented on top of
-  ``cryptography.hazmat.primitives``.
-* ``cryptography.hazmat.primitives``: This packages contains low level
-  algorithms, things like ``AES`` or ``SHA1``. This is implemented on top of
-  ``cryptography.hazmat.backends``.
-* ``cryptography.hazmat.backends``: This package contains bindings to low level
-  cryptographic libraries. Our initial target is OpenSSL.

 We recommend using the recipes layer whenever possible, and falling back to the
 hazmat layer only when necessary.
