+title: Kotlin Script dependency versions
+description: Kotlin Script dependency versions support in Renovate
+---
+
+Renovate supports upgrading dependencies in [Kotlin Script](https://github.com/Kotlin/KEEP/blob/master/proposals/scripting-support.md) files.
+These are self-contained scripts where one can write Kotlin code with JVM backend, and compilation happens when the
+scripts are ran. For example:
+
+```kotlin
+#!/usr/bin/env kotlin
+@file:Repository("https://jitpack.io")
+@file:DependsOn("com.github.krzema12:github-actions-kotlin-dsl:main-SNAPSHOT")
+@file:DependsOn("org.eclipse.jgit:org.eclipse.jgit:4.6.0.201612231935-r")
+@file:DependsOn("org.jetbrains.lets-plot:lets-plot-kotlin-jvm:3.0.2")
+
+println("Hello world!")
+
+// ...
+```
+
+By default, Renovate scans files only with `.main.kts` extension and not `.kts`, to avoid ambiguity with Gradle config
+files that have `.gradle.kts` extension. As there are cases where just `.kts` extension or no extension is used,
+Renovate can be [configured](https://docs.renovatebot.com/configuration-options/) to scan also these:
+
+```json
+{
+ "kotlin-script": {
+ "fileMatch": ["^.*\\.kts$"]
+ }
+}
+```
