# Kotlin in Gitpod

To work with Kotlin in Gitpod, you will need to properly configure your repository. Here is how to do it.

## Installing Kotlin

To install Kotlin in Gitpod add the following to your [.gitpod.Dockerfile](/classic/user/configure/workspaces/workspace-image):

```dockerfile theme={null}
RUN brew install kotlin
```

A full example could look like this:

```dockerfile theme={null}
FROM gitpod/workspace-full

USER gitpod
RUN brew install kotlin
```

## VS Code extensions

### Kotlin Language

This extension provides Kotlin language support for Gitpod and other IDEs, with:

* Syntax highlighting
* Code snippets
* Region code folding

To get it, open Gitpod's **Extensions** panel (left vertical menu), then search for "Kotlin" and install the extension by Mathias Fröhlich for your project. Next, commit the [.gitpod.yml](/classic/user/references/gitpod-yml) file that was automatically created (or updated) by Gitpod.

### Code Runner

While this extension isn't Kotlin-specific, but allows to run code snippets in many different languages, including Kotlin.

To get it, open Gitpod's Extensions panel, then search for "Code Runner" and install it for your project.
