Installing Scala is even simpler.

Go to http://bit.ly/2Am757R and download the sbt-*.*.*.tgz archive (at the time of writing this book, the latest version is sbt-1.0.4.tgz). Next, in your Terminal, navigate to the folder you have just downloaded Scala to and issue the following commands:

tar -xvf sbt-1.0.4.tgz
sudo mv sbt-1.0.4/ /opt/scala/

That's it. Now, you can skip to the Updating PATH section in this recipe to update your PATH.
