+To use this android instrumentation library in your application, you will first need to add
+a dependency in your application's `build.gradle.kts`. We publish a bill of materials (BOM) that
+helps to coordinate versions of the opentelemetry-android components and the upstream
+`opentelemetry-java-instrumentation` and `opentelemetry-java` dependencies. We recommend
+using the bom as a platform dependency, and then omitting explicit version information
+from all other opentelemetry dependencies:
 
 ```kotlin
 dependencies {
     //...
-    implementation("io.opentelemetry.android:android-agent:0.12.0-alpha")
+    api(platform("io.opentelemetry.android:opentelemetry-android-bom.12.0-alpha"))
+    implementation("io.opentelemetry.android:android-agent") // Version is resolved thru bom
     //...
 }
 ```
