New to this, how to use Tag please

[nicsolo]

Hi, apologies in advance for the seemingly easy question and need for advice but I'm new to this and require some assistance. I need to rename some tracks and a couple of albums that my Bluesound CD ripper didn't recognise. I have no idea how to use Tag and was hoping for some pointers please even an online user guide? Thank you

Tag will not do anything to an actual CD.

Ok sorry, I should have made that clear, I'm connected to my NAS drive where my Music is stored and trying to rename the unknown tracks and albums. I'm not changing the actual CD.

Appreciate any assistance
