+This is a Kotlin Multiplatform project targeting Desktop, Server.
+
+* `/composeApp` is for code that will be shared across your Compose Multiplatform applications.
+  It contains several subfolders:
+  - `commonMain` is for code that’s common for all targets.
+  - Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name.
+    For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app,
+    `iosMain` would be the right folder for such calls.
+
+* `/server` is for the Ktor server application.
+
+* `/shared` is for the code that will be shared between all targets in the project.
+  The most important subfolder is `commonMain`. If preferred, you can add code to the platform-specific folders here too.
+
