Reference is the orientation layer over AXSG's generated API. Use it when you know the package, assembly, namespace, or feature family and want the shortest path to the correct API tree and companion narrative docs.
Start here when
you need to choose between multiple shipped packages
you already know an assembly or namespace name and want the right generated API route
you need to map a feature to its primary package, runtime layer, and editor/tooling support
you are extending AXSG and need the package and namespace boundaries before opening raw API pages
