Hello,
I've installed Elasticsearch on the new Ubuntu 16, Download and install the Debian package manually, and the service seems to be running fine.

I've been going through the documentation, and took the required steps of setting the configuration where needed, but I'm a bit at a loss now on what to do.
Could someone give me a hand on what to check and change?
