Create Gradle plugin using Kotlin

Hello community.

I'd like to create my own Gradle plugin (not an IntelliJ plugin), written in Kotlin, to use it in my own projects.

I searched everywhere and there is information on how to create one in Java, using the java-gradle-plugin, and there's also groovy-gradle-plugin (which I suspect it's about creating a plugin in Groovy). I did have success with the java-gradle-plugin, but doing simple things in Java was already too complicated and I didn't even have the references of the Kotlin language,  which I needed for my plugin.

Is there any template/demo project that shows how to write one? Or isn't there any?

Thank you!
