+### Scalafix in the editor
+
+[Scalafix](https://scalacenter.github.io/scalafix/) is a linting and refactoring tool, which
+aims to help automate migration between different Scala compiler and library versions.
+Currently, the primary way to interact with Scalafix is in batch mode through a command-line interface.
+However, many users have requested the ability to use Scalafix interactively through an editor.
+
+A [proof-of-concept integration](https://geirsson.com/assets/metals/) running Scalafix from VS Code 
+through the [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) is already working.
+Many popular IDE refactorings like "Move class" and "Organize imports" are missing, however.
+
+The scope of this GSOC project would be to implement new Scalafix refactoring rules to be used from an editor.
+The project can start small with simple refactorings, and gradually step up as progress happens.
+Scalafix is a fast moving project, so you will be working in a codebase with multiple contributors.
