 ### About
 
-A rust implementation of the PQC scheme Crystals (https://pq-crystals.org/).
+A pure rust implementation of the Module-Lattice-based standards [ML-KEM](https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.203.ipd.pdf) and [ML-DSA](https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.204.ipd.pdf), also known as the PQC scheme [Crystals](https://pq-crystals.org/).
 
-This package consists of a library (`enc_rust`), and (soon :TM:) a binary wrapper. The library contains implementations for both Kyber and Dilithium.
+This package consists of a library (`enc_rust`), and (soon :TM:) a binary wrapper. The library currently contains implementations for ML-KEM (Kyber), and will in the future also support ML-DSA (Dilithium).
+
+### Why enc_rust?
+
+enc_rust aims to provide a secure, efficient, and ergonomic solution to any problem that requires quantum secure cryptography.
+
+- No unsafe code
+- `no_std` compatible
+- ergonomic
+
+enc_rust currently supports ML-KEM as a sole mechanism, but will provide:
+
+- ML-KEM in hybrid with x25519
+- ML-DSA
+- ML-DSA in hybrid with Ed25519
