 In addition to the exercism CLI and your favorite text editor, practicing with Exercism exercises in Scala requires:
 
-* Recent build of the Java 8 Platform, such as [OpenJDK](http://openjdk.java.net/install/) or [Oracle Java JDK](http://www.oracle.com/technetwork/java/javase/downloads/index.html) 
-* [Download](http://www.scala-sbt.org/release/docs/Setup.html) and install the Simple Build Tool (`sbt`)
+* Java Development Kit (JDK) 11 or later. Use your preferred vendor or grab one from [Adoptium](https://adoptium.net/)
+* [Scala 2.13.x](https://www.scala-lang.org/download/scala2.html)
+* [sbt 1.6.x](https://www.scala-sbt.org/download.html)
+
+If you don't want install these various dependencies by hand, consider using [SDKMAN](https://sdkman.io/) to manage your java and java-adjacent development tools and libraries.
