 # Installation
 
 {% include aside content='You might notice there is as an `imagej` package available from your package manager. Please be aware that this provides the original [ImageJ](/software/imagej) only, packaged by a third party. You will not have access to any [ImageJ2](/software/imagej2)-specific features such as [parameterized scripts](/scripting/parameters), and you will likely have permissions errors because it is a system-wide ImageJ installation.' %}
 
 The following steps describe how to install Fiji on a Raspberry Pi:
 
-1.  Open the terminal.
-2.  Install Java 8 on your Pi (`sudo apt-get install openjdk-8-jre`).
-3.  Choose Java 8 (`sudo update-alternatives --config java`).
-4.  Verify it works using `java -version`.
-5.  Download and install the [platform-independent "no JRE" distribution of Fiji](http://downloads.imagej.net/fiji/latest/fiji-nojre.zip).
-6.  Download the [ImageJ.sh](https://github.com/imagej/imagej2/blob/-/bin/ImageJ.sh) shell script
-7.  Move the `ImageJ.sh` file to the `Fiji.app` folder
-8.  Set the executable bit (`chmod +x ImageJ.sh`)
-9.  Run it (`./ImageJ.sh`) to launch Fiji.
+1.  Open the terminal
+2.  Install [SDKMAN!](https://sdkman.io/)
+3.  Verify it works:
 
-You may also need to disable (comment out) `assistive_technologies=org.GNOME.Accessibility.AtkWrapper` in `/etc/java-8-openjdk/accessibility.properties`.
+        sdk version
+4.  Install Java 8:
 
+        sdk install java 8.0.402-tem
+5.  Verify it works:
+
+        java -version
+
+7.  Download and install the [platform-independent "no JRE" distribution of Fiji](http://downloads.imagej.net/fiji/latest/fiji-nojre.zip)
+8.  Download the [ImageJ.sh](https://github.com/imagej/imagej2/blob/-/bin/ImageJ.sh) shell script
+9.  Move the `ImageJ.sh` file to the `Fiji.app` folder
+10.  Set the executable bit:
+
+         chmod +x ImageJ.sh
+11.  Launch Fiji:
+
+         ./ImageJ.sh
 Note that the shell script supports only a subset of the functionality of the native [ImageJ Launcher](/learn/launcher), but it should be able to run ImageJ successfully.
