How to download MinimServer to Synology

[nyron59]

I have newly acquired a Synology DS 216+. I am trying to follow the instructions to download (1) Java 8 and (2) MinimServer. I've come up against a couple of issues straightaway:

1. If I go to Utilities, as directed, I cannot see Java 8
2. Similar point with MinimimServer

I suspect that new Synology NAS' no longer have these within the package. How do I go about downloading them from the Internet and where do I install them for my music?
