+### Tips and tricks
+
+#### Copy generated icons into source folder instead of build folder
+
+To keep generated icons in your source folder (e.g. for version control), you can create custom Gradle tasks to sync
+the generated files after the generation task.
+
+```kotlin
+val copyTask = tasks.register<Copy>("copyValkyrieIcons") {
+  dependsOn(tasks.named("generateValkyrieImageVector"))
+
+  from(layout.buildDirectory.dir("generated/sources/valkyrie/commonMain"))
+  into(layout.projectDirectory.dir("src/commonMain/kotlin"))
+}
+
+val cleanTask = tasks.register<Delete>("cleanValkyrieGenerated") {
+  delete(layout.buildDirectory.dir("generated/sources/valkyrie"))
+}
+
+tasks.register("updateValkyrieIcons") {
+  dependsOn(copyTask)
+  finalizedBy(cleanTask)
+}
+```
