title: Building Dotty with Intellij IDEA
---
Dotty compiler support is available in the [Scala plugin nightly] starting
from 2.2.39. You need to install [IDEA 2016.1] to try it.
## To create a new project with Dotty
1. Open New Project dialog and select `Scala` > `Dotty`
2. Proceed as usual and don't forget to create or select Dotty SDK.
## To compile an existing Scala project with Dotty
1. Create a new Dotty SDK:
`Project Structure` > `Global libraries` > `New Global Library` > `Dotty SDK`
2. Replace Scala SDK with Dotty SDK in:
`Project Structure` > `Modules` > `Dependencies`
Java 1.8 should be used as the Project/Module SDK. You also need to enable the
Scala Compile Server to use Dotty compiler.
## Notes
* Dotty support is experimental, many features including code highlighting and
worksheet are not ready yet.
* You can download the latest version of Dotty without creating a new Dotty SDK
with the `Update snapshot` button in the Dotty SDK library settings.
* Please report any problems to the [IntelliJ Scala issue tracker] or write
to the [IntelliJ Scala gitter]
