# Welcome!

This Kotlin template lets you get started quickly with a simple working example using Maven and JUnit. If it is your first contribution then you should have a look at the [Getting Started](https://tech.io/doc/getting-started-create-playground) document.

The source code is on [GitHub](https://github.com/TechDotIO/kotlin-template), please feel free to come up with proposals to improve it.

A simple Java + Maven + JUnit project dedicated to run the programming exercise above. A project relies on a Docker image to run. You can find images on the [Docker Hub](https://hub.docker.com/explore/) or you can even [build your own](https://tech.io/doc/reference-runner).
