+# OpenTelemetry TraceResponse Propagator
+
+**Note:** This package is experimental as `traceresponse` is currently an editors' draft.
+
+This package provides a [Trace Context HTTP Response Headers Format](https://w3c.github.io/trace-context/#trace-context-http-response-headers-format)
+propagator to inject the current span context into Response datastructures.
+
+The main goal is to allow client-side technology (Real User Monitoring, HTTP Clients) to record
+the server side context in order to allow referencing it.
+
+## Requirements
+
+* OpenTelemetry SDK and exporters (required to actually export traces)
+
+Optional:
+* OpenTelemetry extension (Some instrumentations can automatically use the `TraceResponsePropagator`)
+
+## Usage
+
+Assuming there is an active `SpanContext`, you can inject it into your response as follows:
+
+```php
+// your framework probably provides a datastructure to model HTTP responses
+// and allows you to hook into the end of a request / listen to a matching event.
+$response = new Response();
+
+// get the current scope, bail out if none
+$scope = Context::storage()->scope();
+if (null === $scope) {
+    return;
+}
+
+// create a PropagationSetterInterface that knows how to inject response headers
+$propagationSetter = new class implements OpenTelemetry\Context\Propagation\PropagationSetterInterface {
+    public function set(&$carrier, string $key, string $value) : void {
+        $carrier->headers->set($key, $value);
+    }
+};
+$propagator = new TraceResponseProgator();
+$propagator->inject($response, $propagationSetter, $scope->context());
+```
+
+## Installation via composer
+
+```bash
+$ composer require open-telemetry/opentelemetry-propagation-traceresponse
+```
+
+## Installing dependencies and executing tests
+
+From TraceResponse subdirectory:
+
+```bash
+$ composer install
+$ ./vendor/bin/phpunit tests
+```
