how to install scala 3?

[xhudik]

Hi guys,
a newbie question: i went through a lot of documentation about scala3/dotty - how to install it but I didnt find any real commands how to do it. While: https://docs.scala-lang.org/scala3/getting-started.html mentions cs as a standard tool - after installation I ended up with scala 2 on my system.

When I checked your documentation - i learned how to install various version of java but nothing about scala versioning. Can you help me here - it might well be that I missed something.

Questions:

1. how to install scala 3 via cs
2. how to install various scala versions via cs (can they live in parallel)?

thank you, Tomas

Hi,
So when one "installs" Scala, we don't really install the compiler, but rather build tool launchers (typically sbt, sometimes mill). cs setup, mentioned in your link, can install those. cs setup also installs a scala launcher, but it's not used when you run sbt for example, and doesn't prevent using any other Scala version from sbt or mill.

To get help about "installing Scala", I'd recommend asking on https://users.scala-lang.org or maybe https://gitter.im/scala/scala, which have a larger audience than the coursier issues or discussion.
