+========
+
+.. currentmodule:: cryptography.hazmat.bindings
+
+``cryptography`` aims to provide low-level CFFI based bindings to multiple
+native C libraries. These provide no automatic initialisation of the library
+and may not provide complete wrappers for its API.
+
+Using these functions directly is likely to require you to be careful in
+managing memory allocation, locking and other resources.
