 Crypto library
 ==============
 
-``lib/crypto/`` provides faster and easier access to cryptographic algorithms
-than the traditional crypto API.
+The Linux kernel's crypto library (``lib/crypto/``) provides kernel-internal
+users of cryptographic algorithms with faster and easier access to those
+algorithms than the traditional kernel crypto API.
 
 Each cryptographic algorithm is supported via a set of dedicated functions.
 "Crypto agility", where needed, is left to calling code.
