That is true, but in this case, BNB is kind of a subset, a plugin of sorts.
I’m wondering how I’m supposed to build upon BNB. I could edit the variables/settings files, but that would mean they would be overwritten if I would like to upgrade to a later version of BNB later, or that I’d have a lot of work to do if I don’t want to lose my changes.
I think it’s odd that BNB, which is so heavily dependent on file/folder structure, doesn’t tell me how to best organize my own files when I build upon it.
