Layer background

I think I answered most of this here:

Background usage in the layers column

Hi, I am new to this software and want to understand more, why in the layers column there is a layer called “Background” when I load Krita? I know what layers are and how to add them etc and use them, but when looking at YouTube tuition videos, I can see no evidence of a “Background” layer being in the layers column. Does it serve a different purpose that an ordinary layer; do I need it and; can I delete it and just work on the layers I have added?

For animation work, use ‘background as raster layer’ and don’t draw/paint anything on the background layer. it is locked by default for a very good reason.
Use transparent paint layers for painting your animated characters.
