Noob here with some questions.

Hey,

Here is a link to a FAQ that covers your questions
https://forum.cuberite.org/showthread.php?tid=1596

Just to add for enabling Plugins, you have a file named settings.ini and there is a section named [Plugins], there you add Plugin=<plugin folder name>

For the permissions look into the FAQ link.

If you have still questions, ask

Good luck,
