+# Hummingbird — Swift HTTP Framework
+
+[Hummingbird](https://github.com/hummingbird-project/hummingbird) is a lightweight, flexible HTTP server framework written in Swift, built on top of [SwiftNIO](https://github.com/apple/swift-nio).
+
+## Why Hummingbird?
+
+- **SwiftNIO-based**: Non-blocking I/O with Swift's structured concurrency
+- **Minimal dependencies**: Designed to be lightweight with opt-in extensions
+- **Modern Swift**: Uses async/await throughout
+- **SSWG incubated**: Part of the Swift Server Work Group ecosystem
+
+## Implementation Notes
+
+- Uses Swift 5.10 with whole-module optimization
+- SQLite via [SQLite.swift](https://github.com/stephencelis/SQLite.swift) for the `/db` endpoint
+- Pre-cached JSON responses for `/json` and `/compression` endpoints
+- Static files loaded into memory at startup
