-In the usual case, you just need to include the dependency with the concrete components sending data to the backend. Currently,
-the only such dependency is `jaeger-thrift`. It transitively brings the `jaeger-core` dependency.
+In the usual case, you just need to include the following dependency to your project:
 ```xml
 <dependency>
     <groupId>io.jaegertracing</groupId>
-    <artifactId>jaeger-thrift</artifactId>
