New User - few questions

Is there a New User Guide or something that provides an overview to the logic around “Libraries” and “Collections”, etc? I have a decent sized library of files, but like most people I’ve been listening to a lot of Tidal lately, and frankly don’t really understand the need for a division between things “in my collection” vs not. I just want an easy way to bookmark the things I enjoy as I find them so I can find them later. Isn’t this how favorites should work? Why do I need to add them to a collection before bookmarking them? I have no doubt you’ve given this careful thought, so an overview of your solution may save me from getting frustrated. User forums are great, but overwhelming in terms of volume. Some basic welcome doc-type info would be helpful if you have it.
