-    scrypt provides bindings to Colin Percival's `scrypt` 
+    This package provides bindings to Colin Percival's `scrypt` 
     implementation (<http://www.tarsnap.com/scrypt.html>). Scrypt is a key
     derivation function designed to be far more secure against hardware
     brute-force attacks than alternative functions such as PBKDF2 or bcrypt.
