+== OpenTracing Example
+
+=== Introduction
+
+This example shows how to use Camel with OpenTracing to trace all
+incoming and outgoing Camel messages.
+
+The example uses a ElastiCo APM Client.
+
+Route client -> service1 using HTTP.
+
+=== Before you start
+
+You need to configure EAK stack - Elasticsearch, APM Server and Kibana
+Please follow
https://www.elastic.co/guide/en/apm/get-started/current/install-and-run.html to
get up and running
+
+=== Build
+
+You will need to compile this example first:
+
+[source,sh]
+----
+$ mvn compile
+----
+
+=== Run the example
+
+[source,sh]
+----
+$ mvn compile spring-boot:run
+
+The client application explicitly instantiates and initializes the
+implementation
+
+=== View results
+After seeing in console messages from timer, visit Kibana to view traces -
+http://localhost:5601/app/apm#/services/Service1Application/transactions/
+select any transaction and click "View full trace"
+
+=== Help and contributions
+
+If you hit any problem using Camel or have some feedback, then please
+https://camel.apache.org/support.html[let us know].
+
+We also love contributors, so
+https://camel.apache.org/contributing.html[get involved] :-)
+
+The Camel riders!
