+# Woo — Common Lisp HTTP Server
+
+[Woo](https://github.com/fukamachi/woo) is a fast, non-blocking HTTP server for Common Lisp, built on [libev](http://software.schmorp.de/pkg/libev.html). It runs on [SBCL](http://www.sbcl.org/) (Steel Bank Common Lisp), which compiles to native machine code.
+
+## Why Woo?
+
+- **First Lisp-family entry** in HttpArena
+- Built on libev for non-blocking I/O with multi-worker process model
+- SBCL compiles CL to native code — no interpreter overhead
+- Solo developer [@fukamachi](https://github.com/fukamachi) has maintained it since 2014
+- Uses the [Lack](https://github.com/fukamachi/lack)/[Clack](https://github.com/fukamachi/clack) interface — the Common Lisp equivalent of Ruby's Rack or Python's WSGI
+
+## Architecture
+
+- **Runtime:** SBCL (native compiled)
+- **Event loop:** libev (non-blocking)
+- **Workers:** Multi-process (one per CPU core)
+- **JSON:** [Jonathan](https://github.com/Rudolph-Miller/jonathan) (fast JSON encoder/decoder)
+- **Compression:** [Salza2](https://www.xach.com/lisp/salza2/) (gzip)
+- **SQLite:** [cl-sqlite](https://github.com/dmitryvk/cl-sqlite)
+
+## Build
+
+The Docker build compiles everything into a standalone SBCL image (~50-80 MB compressed) that includes the full Lisp runtime and all dependencies. No Quicklisp needed at runtime.
+
+```bash
+docker build -t httparena-woo .
+docker run -p 8080:8080 -v /path/to/data:/data httparena-woo
+```
