 # http-transport
 
 Implementations of HTTP transport protocols, compatible with other Handy-Http components.
+
+## HTTP/1.1
+
+Use the `Http1Transport` implementation of `HttpTransport` to serve content
+using the HTTP/1.1 protocol. See the example below:
+
+```d
+import handy_http_primitives;
+import handy_http_transport;
+
+class MyHandler : HttpRequestHandler {
+    void handle(ref ServerHttpRequest req, ref Server HttpResponse resp) {
+        response.status = HttpStatus.OK;
+        response.headers.add("Content-Type", "text/plain");
+        response.outputStream.writeToStream(cast(ubyte[]) "Hello world!");
+    }
+}
+
+void main() {
+    HttpTransport tp = new Http1Transport(new MyHandler(), 8080);
+    tp.start();
+}
+```
