 plugins for the Ktor client and server respectively. For the source code, see
 the [repository on GitHub](https://github.com/open-telemetry/opentelemetry-java-instrumentation/tree/main/instrumentation/ktor).
 
-This project contains extension functions for plugins that allow you to write code in the Ktor DSL style.
+This project contains examples of how to use the `KtorClientTracing` and `KtorServerTracing` plugins.
 
-Take the following code as an example:
-
-```kotlin
-install(KtorServerTracing) {
-    ...
-    addAttributeExtractor(
-        object : AttributesExtractor<ApplicationRequest, ApplicationResponse> {
-            override fun onEnd(
-                attributes: AttributesBuilder,
-                context: Context,
-                request: ApplicationRequest,
-                response: ApplicationResponse?,
-                error: Throwable?
-            ) {
-                attributes.put("end-time", Instant.now().toEpochMilli())
-            }
-        }
-    )
-    ...
-}
-```
-
-Rewritten in Ktor DSL style, it looks like the following:
-
-```kotlin
-install(KtorServerTracing) {
-    ...
-    attributeExtractor {
-        onEnd {
-            attributes.put("end-time", Instant.now().toEpochMilli())
-        }
-    }
-    ...
-}
-```
-
-You can find all extensions for the client plugin `KtorClientTracing` in
-the [extractions](./client/src/main/kotlin/opentelemetry/ktor/example/plugins/opentelemetry/extractions/) folder. \
-And you can find all extensions for the server plugin `KtorServerTracing` in
-the [extractions](./server/src/main/kotlin/opentelemetry/ktor/example/plugins/opentelemetry/extractions/) folder.
