 WurstScript and its related tools require Java 11+ to run. Editor support is provided via a VSCode extension.
 
-### Download JRE
+### Java
 
 [_ _{: .fa .fa-download} Download Java from Adoptium](https://adoptium.net/?variant=openjdk11){: .btn .btn-orange}
 
 Download the Java Runtime appropriate for your system and follow the installation procedure.
 
-Once finished, continue to the next step.
+### VSCode
 
-### Verify Java Installation
-
-Many tasks rely on a environment variable called **JAVA_HOME** which might not have been set by the installer.
-To verify your installation, open a command prompt and enter `java -version`.
-
-A valid installation will return something like this:
-
-```powershell
-> java -version
-openjdk version "11.0.17" 2022-10-18
-OpenJDK Runtime Environment Temurin-11.0.17+8 (build 11.0.17+8)
-OpenJDK 64-Bit Server VM Temurin-11.0.17+8 (build 11.0.17+8, mixed mode)
-```
-
-The major version should be `11` or higher. If it is lower, you must update your Java installation.
-
-If you get an error or get a lower versions displayed, even though you installed a newer one, your **JAVA_HOME** is either missing or configured wrong.
-
-Refer to this [_ _{: .fa .fa-external-link-square} Windows tutorial](https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html) in order to setup your **JAVA_HOME** correctly.

 ## Install Wurstscript
 
 Now we will setup a Wurst compiler environment and create a project using the the WurstSetup, also known as `grill`.
 
 [_ _{: .fa .fa-download} Download WurstSetup](https://grill.wurstlang.org/hudson/job/WurstSetup/lastSuccessfulBuild/artifact/downloads/WurstSetup.jar){: .btn .btn-green}
 
-The Wurstsetup can be used either from the commandline or as a graphical application.
-
-## Commandline
-
-Usage by invoking `grill` via the commandline is recommended and provides a similar user experience to tools such as `npm`, `maven`. etc. To use the setup from the commandline you need to complete the initial installation once.
-After that you can invoke `grill` from your commandline.
-
-### Initial installation
-
-For the first time you have to run the .jar file directly, because the executable hasn't been installed yet.
-
-`java -jar WurstSetup.jar install wurstscript`
-
-Now you need to add the `~/.wurst` folder to your PATH environment variable, so you can use it from the commandline.
-Refer to this [tutorial](https://www.java.com/en/download/help/path.xml). On Windows 10, the result should look like this:

+Download WurstSetup and perform installation by running `java -jar WurstSetup.jar install wurstscript` or double-clicking to start the graphical user interface.
 
-The `grill` command should now be recognized by your terminal of choice.
+Now you need to add the `~/.wurst` folder to your PATH environment variable, so that `grill` is recognized from the commandline.

+## Commandline Usage
 
-If not, a restart might be required.
+Using `grill` from the commandline you can now start with generating a new project or installing an existing project. The user experience is similar to tools such as `npm`, `mvn`. etc.
 
 ### Updating the Compiler
 
 Use the special `wurstscript` keyword to install or update wurst on your system for the current user.

 Use `generate` to create new projects. The project will be generated in a folder inside your current location with the name provided.
