+# Iroh
+
+> A peer-to-peer QUIC library for establishing direct connections between devices. Built in Rust by n0-computer.
+
+## Overview
+
+Iroh is a library for establishing the most direct QUIC connection possible between two devices. It provides "dial by public key" functionality, where you connect to nodes using their NodeId (32-byte ed25519 public key) rather than IP addresses. The library handles NAT traversal, hole punching, and relay fallbacks automatically.
+
+Iroh is compiled & tested for nearly all common platforms: Windows, MacOS, Linux, Android, iOS, etc. It runs on devices as small as an ESP32, as well as datacenter-grade servers.
+
+## Key Features
+
+- **Direct P2P connections**: Establishes direct QUIC connections whenever possible
+- **NAT traversal**: Automatic hole punching and relay server fallback
+- **Cryptographic identity**: Each node identified by ed25519 public key (NodeId)
+- **QUIC-based**: Built on QUIC for encryption, authentication, and stream multiplexing
+- **Composable protocols**: Compose multiple protocols for pluggable functionality from a community-driven set
