+# Example of Auto instrumentation of HTTP server + Kafka producer + Kafka consumer + Manual span
+
+This example shows a trace being generated which is composed of a HTTP server handler which produces
+a batch of 2 message to different kafka topics, and a single consumer consuming one of these messages.
+The consumer generate a manual span for each message it handles, this span is visible as the son of the consumer span.
+
+To run the example, bring up the services using the command.
+
+```
+docker compose up 
+```
+
+After the services are up, you can hit the server using the below command
+```
+curl localhost:8080/produce
+```
+Which will produce a batch of 2 messages.
+Every hit to the server should generate a trace that we can observe in [Jaeger UI](http://localhost:16686/)
