+If your application uses Jetpack Compose, you can use the <PlatformLink to="/kotlin-compiler-plugin/">Sentry Kotlin Compiler Plugin</PlatformLink> to see the function names of your `@Composable` elements. You must add the plugin to all modules that contain `@Composable` elements.

+```groovy {filename:app/build.gradle}

+
+The [Sentry Kotlin Compiler Plugin](https://github.com/getsentry/sentry-android-gradle-plugin) is an addition to the Sentry Android Gradle plugin and offers improvements to existing SDK features. As of now the main focus of the plugin is to improve apps which utilize Jetpack Compose by automatically tagging `@Composable` functions.

+
+## How it works
+
+Given a `@Composable` function:
+
+```kotlin
+@Composable
+fun LoginScreen() {
+    Column() {
+        // ...
+    }
+}
+```
+
+The Sentry Kotlin Compiler Plugin will transform it into the following:
+
+```kotlin
+@Composable
+fun LoginScreen() {
+    Column(modifier = Modifier.sentryTag("LoginScreen")) {
+        // ...
+    }
+}
+```
+
+## Setup
+
+### Install
+
+Kotlin Compiler plugins are executed during compilation and thus need to be applied to _every_ relevant Gradle module. Add the following to e.g. your `app/build.gradle`:
+
+```groovy {filename:app/build.gradle}
+plugins {
+  id "io.sentry.kotlin.compiler.gradle" version "{{@inject packages.version('sentry.kotlin.compiler-plugin', '3.0.0') }}"
+}
+```
+
+```kotlin {filename:app/build.gradle.kts}
+plugins {
+  id("io.sentry.kotlin.compiler.gradle") version "{{@inject packages.version('sentry.kotlin.compiler-plugin', '3.0.0') }}"
+}
+```
+
+### Configuration
+
+As of now no additional steps are necessary. Checkout the docs for <PlatformLink to="/enriching-events/viewhierarchy">View Hierarchy</PlatformLink> and <PlatformLink to="/performance/instrumentation/automatic-instrumentation/#user-interaction-instrumentation">User Interaction Tracing</PlatformLink> to see which features the Sentry Kotlin Compiler Plugin improves.

+##### Automatic `@Composable` tagging using the Sentry Kotlin Compiler Plugin
+
+<Note>
+
+The Sentry Kotlin Compiler plugin is considered _experimental_. Give it a try and provide early feedback [on GitHub](https://github.com/getsentry/sentry-android-gradle-plugin).
+
+</Note>
+
+The <PlatformLink to="/kotlin-compiler-plugin/">Sentry Kotlin Compiler Plugin</PlatformLink> can automatically enrich your `@Composable` functions during compilation with a tag name, based on the function name of your `@Composable`. In order to use this feature, the Sentry Kotlin Compiler plugin needs to be applied to all modules, which contain `@Composable` elements.
+
+```groovy {filename:app/build.gradle}
+plugins {
+  id "io.sentry.kotlin.compiler.gradle" version "{{@inject packages.version('sentry.kotlin.compiler-plugin', '3.0.0') }}"
+}
+```
+
+```kotlin {filename:app/build.gradle.kts}
+plugins {
+  id("io.sentry.kotlin.compiler.gradle") version "{{@inject packages.version('sentry.kotlin.compiler-plugin', '3.0.0') }}"
+}
+```
+
 #### Transaction Lifetime
 
 The transaction finishes automatically after it reaches the specified [idleTimeout](/platforms/android/configuration/options/#idle-timeout) and all of its child spans are finished. The `idleTimeoout` defaults to `3000` milliseconds (three seconds). You can also disable the idle timeout by setting it to `null`, but the transaction must be finished manually in this case.
