+# [Compose Multiplatform](https://github.com/JetBrains/compose-multiplatform) iOS CocoaPods example
+
+This example showcases using Kotlin Multiplatform shared module in Swift as a CocoaPods framework.
+
+The official Kotlin documentation provides more information on working with CocoaPods:
+* [CocoaPods overview and setup](https://kotlinlang.org/docs/native-cocoapods.html);
+* [Add dependencies on a Pod library](https://kotlinlang.org/docs/native-cocoapods-libraries.html);
+* [Use a Kotlin Gradle project as a CocoaPods dependency](https://kotlinlang.org/docs/native-cocoapods-xcode.html);
+
+
+## Setting up your development environment
+
+To setup the environment, please consult these [instructions](https://github.com/JetBrains/compose-multiplatform-template#setting-up-your-development-environment).
+
+## How to run
+
+Choose a run configuration for an appropriate target in IDE and run it.
