+### Update the wizard plugin
+The compose plugin version used in the wizard above may be out of date. Update the version of the plugin to the latest available by editing the build.gradle.kts file, finding and updating the version information as shown below. (In this example the latest version of the plugin was 0.3.0-build152 and a compatible version of kotlin was 1.4.30. For the latest versions, see the [compose-jb](https://github.com/JetBrains/compose-jb/tags) github site and the JetBrains [Kotlin](https://kotlinlang.org/) site.)
+```
+plugins {
+    kotlin("jvm") version "1.4.30"
+    id("org.jetbrains.compose") version "0.3.0-build152"
+}
+```

 ### Create new Compose project without the wizard
 
 It is also possible to create Compose project manually.
