+= Graalvm Build Guide
+
+*1. Setup Graalvm*
+
+* Update the file under e.g. C\Projects\IDEasy\settings and add
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+GRAALVM_EDITION=community
+|===
+
+This is necessary as the community edition of graalvm is delivered with a pre-installed native image.
+
+* Open a command-line interface inside a devon installation e.g. C\Projects\IDEasy\workspaces\main
+
+* Install Graalvm using the devonfw-ide with
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+devon graalvm setup
+|===
+
+When the installation is complete, the GRAALVM_HOME environment variable is automatically set to the graalvm installation path e.g. C/Projects/IDEasy/software/extra/graalvm
+
+* Restart your cli
+
+* Add *$GRAALVM_HOME/bin* to your *PATH* environment variable
+
+Bash:
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+export PATH=$GRAALVM_HOME\bin:$PATH
+|===
+
+Powershell (run as Admin):
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+$path = [System.Environment]::GetEnvironmentVariable("Path",[System.EnvironmentVariableTarget]::Machine) +
+$newPath = "$env:GRAALVM_HOME\bin;" + $path +
+[System.Environment]::SetEnvironmentVariable("Path", $newPath,
+[System.EnvironmentVariableTarget]::Machine)
+|===
+
+*2. Install Dependencies*
+
+*2.1 Windows: Install Visual Studio*
+
+* Download Visual Studio from https://visualstudio.microsoft.com/downloads/
+
+* During the installation, make sure to include the "Desktop development with CPP" workload, as this includes the necessary C/C++ compiler
+
+image:images/cppInstall.png[image]
+* If you already have Visual Studio installed, open the Visual Studio installer and click “modifyˮ on your existing installation.
+Then select the C++ workload and click on install.
+
+*2.2 Linux*
+
+Install the zlib development package on your system:
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+sudo apt-get update +
+sudo apt-get install zlib1g-dev
+|===
+
+*3. Build Your Application*
+
+Run the following Maven command inside Intellij to compile your application and create an executable:
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+-B -ntp -Pnative -DskipTests=true package
+|===
+
+image:images/graalvmMvnArgs.png[image]
+
+*Alternatively you can build the project using a cli:*
+
+* Open *PowerShell* and check the java version with
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+java --version
+|===
+
+If the java version is below 17, you need to specify a JDK with version >=17.
+e.g.
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+$env:JAVA_HOME = "C:\Projects\IDEasy\software\java\"
+|===
+
+This command sets the *JAVA_HOME* variable temporarily for the session and will be re-set after you close the shell.
+
+* Run the following Maven command in your project directory where the pom.xml is located to compile your application and create an executable:
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+PATH/TO/MVN/mvn -B -ntp -Pnative -DskipTests=true package
+|===
+
+Example:
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+C:\Projects\IDEasy\workspaces\main\IDEasy> C:\Projects\IDEasy\software\mvn\bin\mvn -B -ntp -Pnative -DskipTests=true package
+|===
+
+Building the application might take up to 10 minutes depending on your machine.
+
+*4. Run your Application* +
+An ideasy executable (e.g. ideasy.exe under windows) should be created under *../workspace/main/IDEasy/cli/target*.
+
+To run the application open a cli and pass your arguments.
+
+Example:
+
+[width="100%",cols="100%",options="header",]
+|===
+a|
+C:\Projects\IDEasy\workspaces\main\IDEasy\cli\target> .\ideasy.exe mvn --version
+|===
