Next, select Set Scala Home, and point it to the location of your Scala install, which was pointed out to us by Homebrew during our earlier install. Β In my case it was:


IntelliJ should autodetect the necessary libraries and documentation path. Fill out the remainder of your projects information (name, etc), and then click Finish to get started.
