 A rust implementation of BIP352: Silent Payments.
 
-Although this library passes all the tests provided in the silent payment BIP,
-it is still very new, so be careful when using this with real funds.
+## About
+
+**Warning: this crate is still new and is my first project doing elliptic curve cryptography!
+Even though it passes the tests provided in the official silent payments BIP,
+review it carefully before using this with mainnet funds.**
+
+This library supports creating and sending to silent payment addresses,
+building on [`secp256k1`](https://docs.rs/secp256k1/latest/secp256k1)
+`PublicKey` and `SecretKey` structs for the interface.
 
 There are two parts to this library: a sender part and a recipient part.
