+## What is Noise?
+
+The [Noise Protocol Framework](https://noiseprotocol.org/) is a widely-used encryption
+scheme that allows for secure communication by combining cryptographic primitives into
+patterns with verifiable security properties.
+
+Learn more at [https://noiseprotocol.org](https://noiseprotocol.org).
+
+## Noise in libp2p
+
+libp2p uses the Noise Protocol Framework to encrypt data between nodes and provide forward
+secrecy. noise-libp2p is an implementation of the Noise Protocol Framework used to establish
+a secure channel between two peers by exchanging keys and encrypting traffic during
+the libp2p handshake process. After a successful Noise handshake, the resulting keys send
+ciphertext messages back and forth over the secure channel. The wire format for these messages
+and the cryptographic primitives used for encryption is specified in the
+[libp2p-noise specification](https://github.com/libp2p/specs/tree/master/noise).
+
+The noise-libp2p protocol ID is `/noise`, and future versions may define new protocol IDs
+using the "/noise" prefix (e.g., `/noise/2`).
