+  "io.kamon" %% "kamon-jaeger" % "2.1.0"
 )
 ```
 
 ### Step 2: Start Reporting your Data
 
-The last step in the process: start reporting your data! You can register as many reporters as you want by using the
-`Kamon.addReporter(...)` function:
-
-```scala
-Kamon.addReporter(new PrometheusReporter())
-Kamon.addReporter(new ZipkinReporter())
-Kamon.addReporter(new Jaeger())
-```
-
+Since version 2.0, Kamon reporters are started automatically through their default configuration.
 Now you can simply `sbt run` the application and after a few seconds you will get the Prometheus metrics
 exposed on <http://localhost:9095/> and message traces sent to Zipkin! The default configuration publishes the Prometheus
 endpoint on port 9095 and assumes that you have a Zipkin instance running locally on port 9411 but you can change these
