Roon: everything you need to know

There have been a number of threads started, and hundreds of posts, asking 101 level questions about Roon.

This overview from WHAT Hi*Fi? is an excellent one. I believe this may / will be valuable to those exploring, considering, and/or starting out with Roon.

I respectfully request posts in this thread focus On Learning about Roon.

There are (other) numerous, better suited threads where opinions (both pro and con) can be expressed, shared and discussed. Thanks!
