 To build an executable jar, simply run (in sbt) `backend/assembly` (that is, the `assembly` task in the `backend` subproject). This will create a fat-jar with all the code, processed javascript, css and html. You can run the jar simply by running java:
 
 ```
-java -jar backend/target/scala-3/bootzooka.jar
+java -jar backend/target/scala-VERSION/bootzooka.jar
 ```
