 Implementation of the double ratchet system/encryption as specified by [Signal][1].
 
+**WARNING! This implementation uses P-256 NOT Curve25519 as specified by Signal!**

 The implementation follows the cryptographic recommendations provided by [Signal][2].
 The AEAD Algorithm uses a constant Nonce. This might be changed in the future.

 ## Features
 
-The crate supports a feature for better performance: ring. If feature is enabled the crate switches
+Currently the crate only supports one feature: ring. If feature is enabled the crate switches
 to ring-compat and uses ring as backend for Sha512 Hashing. May result in slightly better performance.

-For WASM support enable the feature `wasm`.
