+## Web Server Middleware for Dart
+
+## Introduction
+
+**Shelf** makes it easy to create and compose **web servers** and **parts of web
+servers**. How?
+
+* Expose a small set of simple types.
+* Map server logic into a simple function: a single argument for the request,
+the response is the return value.
+* Trivially mix and match synchronous and asynchronous processing.
+* Flexibliity to return a simple string or a byte stream with the same model.
+
+## Example
+
+See `example/example_server.dart`
+
+```dart
+import 'package:shelf/shelf.dart' as shelf;
+import 'package:shelf/shelf_io.dart' as io;
+
+void main() {
+  var handler = const shelf.Stack().addMiddleware(shelf.logRequests())
+      .addHandler(_echoRequest);
+
+  io.serve(handler, 'localhost', 8080).then((server) {
+    print('Serving at http://${server.address.host}:${server.port}');
+  });
+}
+
+shelf.Response _echoRequest(shelf.Request request) {
+  return new shelf.Response.ok('Request for "${request.pathInfo}"');
+}
+```
