In addition to running the jar file directly, you can also install POL 5 on your operating system.
Ubuntu 16.04
To install POL 5 on Ubuntu, you need to execute the deb file inside the target/packages folder of the phoenicis-dist project (see Build for more information).
If you already have POL 5 installed through a deb file, you can simply override your old installation by executing a newer deb POL 5 installation file. This will replace the old installation with a newer one.
