 # sha3-d
 
-SHA-3 library written entirely in D implementing Keccack-f\[1600,24] and is fully
-compatible with the Phobos Digest API (std.digest).
+This is a SHA-3 library written entirely in D. It implements the Keccak
+hashing algorithm and it is fully compatible with the Phobos Digest API (std.digest).
 
 Introduced in 2015, SHA-3 is the latest member of the SHA family. SHA-3 is
 already used in production-ready projects worlwide, including SQLite3 for both
 internal and download integrity operations. For more information about SHA-3,
 consult [NIST FIPS PUB 202](http://dx.doi.org/10.6028/NIST.FIPS.202) (PDF).
