+WebGoat now has Docker support for x86 and ARM (raspberry pi).
+### Docker on x86
+On x86 you can build a container with the following commands:
 
 ```Shell
 cd WebGoat/
 mvn package
 cd webgoat-container
+mvn package
 mvn docker:build
 docker tag webgoat/webgoat-8.0 webgoat/webgoat-8.0:8.0
 docker login
 docker push webgoat/webgoat-container
 ```
 
+### Docker on ARM (Raspberry Pi)
+On a Raspberry Pi (it has yet been tested with a Raspberry Pi 3 and the hypriot Docker image) you need to build JFFI for 
+ARM first. This is needed by the docker-maven-plugin ([see here](https://github.com/spotify/docker-maven-plugin/issues/233)):
+
+```Shell
+sudo apt-get install build-essential
+git clone https://github.com/jnr/jffi.git
+cd jffi
+ant jar
+cd build/jni
+sudo cp libjffi-1.2.so /usr/lib
+```
+
+When you have done this you can build the Docker container using the following commands:
+ 
+```Shell
+cd WebGoat/
+mvn package
+cd webgoat-container
+mvn package
+mvn docker:build -Drpi=true
+docker tag webgoat/webgoat-8.0 webgoat/webgoat-8.0:8.0
+docker login
+docker push webgoat/webgoat-container
+```
+
 With the following command you are able to run the Docker container on your local machine:
 
 ```Shell
