Basics tutorial - Kotlin + GRPC

Is there a standalone repo that can be used as a kotlin example for GRPC? I'm having a lot of trouble figuring out how to structure my gradle files when the examples are embedded along side other kotlin code.

The explanation at https://grpc.io/docs/languages/kotlin/basics/ is super useful but I'm finding it quite difficult to follow when starting from scratch (as opposed to pulling a fairly complex repo).
