Suppose I don’t know anything about the core/plugins file hierarchies, because I just came here to make a new theme component. Where do I look to find out? What are the naming conventions for directories and the files inside them?
Just looking at different theme/components circulating around, there are all kinds of different nesting schemes and subdirectories floating around. I have not been able to figure out a pattern, or find any documentation. (E.g., what is the difference between /initializers and /api-initializers and /pre-initializers? 
)
