I am trying to use theme Bootstrap Barrio 5.5.20, and have the associated Bootstrap Barrio 5.5.20 Subtheme also installed and set as the default. I have assumed, without knowing for sure, that this Subtheme is a pre-built subtheme that eliminates the need to manually create a subtheme, is that correct? So if I make changes to the subtheme files, not just CSS but possibly in the number and definition of regions, will future updates to Bootstrap Barrio then flow through and not require any reworking or updating of the subtheme?

Hello all, i just started to use Drupal and im having a very hard time trying to learn it, i want to build me website with it and i want to customize my homepage but i dont understand it. Should i create it as a homepage and put all the html ibside the box or can it be done with theme?
