+
+### ...Or manually
+1. if you don't have Java 8 or 11 installed, download
+Java from [Oracle Java 8](https://www.oracle.com/java/technologies/javase-jdk8-downloads.html), [Oracle Java 11](https://www.oracle.com/java/technologies/javase-jdk11-downloads.html),
+or [AdoptOpenJDK 8/11](https://adoptopenjdk.net/). Refer to [JDK Compatibility](/overviews/jdk-compatibility/overview.html) for Scala/Java compatibility detail.
+1. Install [sbt](https://www.scala-sbt.org/download.html)
+
+## Create a Hello-world project with sbt
+To create a project, you can either use a command-line tool or an IDE.
+If you are familiar with the command line, we recommend that approach.
+
+### Using command-line
+sbt is a build tool for Scala. sbt compiles, runs,
+and tests your Scala code. (It can also publish libraries and do many other tasks.)
+
+1. `cd` to an empty folder.
+1. Run the following command `sbt new scala/hello-world.g8`.
+This pulls the 'hello-world' template from GitHub.
+It will also create a `target` folder, which you can ignore.
+1. When prompted, name the application `hello-world`. This will
+create a project called "hello-world".
+1. Let's take a look at what just got generated:
+
+```
+- hello-world
+ - project (sbt uses this for its own files)
+ - build.properties
+ - build.sbt (sbt's build definition file)
+ - src
+ - main
+ - scala (all of your Scala code goes here)
+ - Main.scala (Entry point of program) <-- this is all we need for now
+```
+
+More documentation about sbt can be found in the [Scala Book](/overviews/scala-book/scala-build-tool-sbt.html)
+and in the official sbt [documentation](https://www.scala-sbt.org/1.x/docs/index.html)
+
+### With an IDE
+You can skip the rest of this page and go directly to [Building a Scala Project with IntelliJ and sbt](/getting-started/intellij-track/building-a-scala-project-with-intellij-and-sbt.html#next-steps)
+
+
+## Open hello-world project
+Let's use an IDE to open the project. The most popular ones are IntelliJ and VSCode.
+They both offer rich IDE features, but you can still use [many other editors.](https://scalameta.org/metals/docs/editors/overview.html)
+### Using IntelliJ
+1. Download and install [IntelliJ Community Edition](https://www.jetbrains.com/idea/download/)
+1. Install the Scala plugin by following [the instructions on how to install IntelliJ plugins](https://www.jetbrains.com/help/idea/managing-plugins.html)
+1. Open the `build.sbt` file then choose *Open as a project*
+
+### Using VSCode with metals
+1. Download [VSCode](https://code.visualstudio.com/Download)
+1. Install the Metals extension from [the Marketplace](https://marketplace.visualstudio.com/items?itemName=scalameta.metals)
+1. Next, open the directory containing a `build.sbt` file. When prompted to do so, select *Import build*.
+
+## Run Hello World
+Open a terminal
+1. `cd` into `hello-world`.
+1. Run `sbt`. This will open up the sbt console.
+1. Type `~run`. The `~` is optional and causes sbt to re-run on every file save,
+allowing for a fast edit/run/debug cycle. sbt will also generate a `target` directory
+which you can ignore.
-There are __two__ main ways people prefer to work in Scala:
-
-* Using an IDE.
-* Using the command line.
-
-The following tutorials will walk you through the setup process for whichever way
-you prefer.
-
-However, if you just want to jump directly into Scala without installing anything, skip the guides on this page and check out:
-
-* [Our interactive introduction to Scala on scala-exercises.com](https://www.scala-exercises.org/scala_tutorial/terms_and_types), or
-* [Scastie](https://scastie.scala-lang.org/), Scala in the browser, with access to all Scala compilers and all published libraries!

-## Setting up and getting started with Scala
-
-### If you prefer working in an IDE...
-
-IntelliJ is the most commonly-used IDE by Scala developers. In this tutorial,
-we'll walk you through downloading and setting up IntelliJ with the Scala
-plugin, and we'll get you started with your first Scala project, complete with
-unit tests!

-* [Building a Scala Project with IntelliJ and sbt](/getting-started/intellij-track/building-a-scala-project-with-intellij-and-sbt.html)
-* [Testing Scala in IntelliJ with ScalaTest](/getting-started/intellij-track/testing-scala-in-intellij-with-scalatest.html)
-
-
-### If you prefer working on the command line...
-
-If you prefer using a text editor like emacs, Vim, Atom, or Sublime Text, then
-the best way to compile, test, and run Scala code is by using _sbt_, Scala's build
-tool.
