+An example of Kotlin Multiplatform todo app with shared Jetpack Compose UI.
 
-To run desktop application execute in terminal: ./gradlew desktop:run
-To run android application you will need to open project in Intellij IDEA or Android Studio and run "android" configuration
+Supported targets: `Android` and `JVM`.
+
+Libraries used:
+- Jetpack Compose - shared UI
+- [Decompose](https://github.com/arkivanov/Decompose) - navigation and lifecycle
+- [MVIKotlin](https://github.com/arkivanov/MVIKotlin) - presentation and business logic
+- [Reaktive](https://github.com/badoo/Reaktive) - background processing and data transformation
+- [SQLDelight](https://github.com/cashapp/sqldelight) - data storage
+
+There are multiple common modules:
+- `utils` - just some useful helpers
+- `database` - SQLDelight database definition
+- `main` - displays a list of todo items and a text field
+- `edit` - accepts an item id and allows editing
+- `root` - navigates between `main` and `edit` screens
