# Installing Prerequisites

Before you start, you must have a few things installed.

1. [Download and install Java](https://www.oracle.com/java/technologies/javase-jdk15-downloads.html) (version 11+ recommended, but 1.8+ should work).
2. [Download and install Scala](https://www.scala-lang.org/download/) (specifically, version 2.12; Scala 2.13 is not yet supported).\
   Note that on the Mac, [the easiest way to install Scala is by using Homebrew](https://formulae.brew.sh/formula/scala@2.12).
3. [Download and install `sbt`](https://www.scala-sbt.org/download.html)†.

   Note that on the Mac, [the easiest way to install `sbt` is by using Homebrew](https://formulae.brew.sh/formula/sbt).

#### Download AutoMan

The easiest way to install AutoMan is to manage your application's build using `sbt` by creating a `build.sbt` file.  This tutorial will explain how to do that, step-by-step.  But if you already know how to use `sbt`, just add the following dependency to your `libraryDependencies` section.

```
"org.automanlang" %% "automan" % "1.4.2"
```

`sbt` will download an AutoMan JAR and store it locally on your machine, along with all of AutoMan's dependencies.

† [Pronounced like this](https://www.youtube.com/watch?v=pQlPjUSj7no). The `sbt` authors [insist "sbt" does not stand for "Scala build tool"](https://www.scala-sbt.org/1.x/docs/Faq.html), so... fair game.
