+You can make your `Initializer` depend on `KoinInitializer` if you need Koin to be setup, and allow to inject dependencies:
+
+```kotlin
+class CrashTrackerInitializer : Initializer<Unit>, KoinComponent {
+
+    private val crashTrackerService: CrashTrackerService by inject()
+
+    override fun create(context: Context) {
