The member area is one dispatcher. Named routes serve the built-in screens, and a last route maps any other path straight onto a template under templates/my-account/, so a members-only page needs no route and no admin configuration. The convention is simple, and the rules around it (what a missing file does, which names are taken, what the template receives) are what a team needs written down.

Start with How the member area is routed, which states the mapping rule and its edges. The built-in member screens is the reference for restyling: each screen's template, its variables, and which ones the framework leaves to you. Adding a custom member page is the three-step procedure, and When the catch-all is not enough covers forms, ids in the path, other access rules and data for scripts. Who may sign in, and how, is in the units before this one; deciding what a signed-in member may see is in the unit after it.
