Added the accounting guide to the README’s “Getting started” docs list so it’s easier to discover alongside other server operations references.
Added a structured “add functionality in layers” section (publishing, communication, collaboration, culture) plus a first-week launch checklist to help new operators grow safely and intentionally.
Updated README.md with a clear “start here” section that points operators to the key docs for creating and extending a tilde host.
Updated docs/shellserver.md to point at the new setup guide and introduced a concise “quick priorities” list for new admins.
