 # Example mill project that compiles using Scala 3
 
-**NOTE**: Scala 3 support in mill is experimental. For now, sbt remains the
-preferred option. See https://github.com/scala/scala3-example-project for an
-example sbt project.
-
 ## Usage
 
-This is a normal mill project. You can compile code with `mill root.compile` and run it
-with `mill root.run`, `mill -i root.console` will start a Scala 3 REPL.
+This is a normal mill project. You can compile code with `mill examples.compile` and run it
+with `mill examples.run`, `mill -i examples.console` will start a Scala 3 REPL.
 
 ### IDE support
 
-Scala 3 comes built-in with IDE support, unfortunately this support is only
-available using sbt and not mill for now, see http://dotty.epfl.ch/docs/usage/ide-support.html
+It's recommended to either use [Metals](https://scalameta.org/metals/) with the
+editor of your choice or [the Scala Plugin for
+IntelliJ](https://blog.jetbrains.com/scala/).
 
 ## Using Scala 3 in an existing project
 
 ### build.sc
-Any version number that starts with `3.` is automatically recognized as Scala 3;
-you don't need to set up anything:
 
 ```scala
 def scalaVersion = "3.1.3"
 ```
 
-#### Nightly builds
-
-If the latest release of Scala 3 is missing a bugfix or feature you need, you may
-wish to use a nightly build. Look at the bottom of the list of
-[releases](https://repo1.maven.org/maven2/org/scala-lang/scala3-compiler_3/)
-to find the version number for the latest nightly build.
-
-## Getting your project to compile with Scala 3
-
-When porting an existing project, it's a good idea to start out with the Scala 2
-compatibility mode (note that this mode affects typechecking and thus may
-prevent some valid Scala 3 code from compiling) by adding to your `build.sc`:
-
-```scala
-def scalacOptions = T {
-  if (Dep.isDotty(scalaVersion()))
-    Seq("-language:Scala2")
-  else
-    Seq()
-}
-```
-
-Using the `Dep.isDotty` method ensures that this option will only be set when
-compiling with Scala 3.
-
-A tool to port code from Scala 2.x to Scala 3 is available; see
-https://scalacenter.github.io/scala-3-migration-guide/docs/tooling/scala-3-migrate-plugin.html
+### Getting your project to compile with Scala 3
 
-If your build contains dependencies that have only been published for Scala 2.x,
-you may be able to get them to work on Scala 3 by replacing:
+For help with porting an existing Scala 2 project to Scala 3, see the
+[Scala 3 migration guide](https://docs.scala-lang.org/scala3/guides/migration/compatibility-intro.html).
