Make it clear the hosted app is free and the data stays local face-gallery.mrbean.dev is public and needs no account, and a backend on your own laptop is fully supported rather than a fallback. Spell out why that is private: the site is static with no server and no storage, so photos only ever reach the backend you point it at, and on localhost they never leave your machine. Also notes the one caveat honestly — the app talks to whatever backend URL you give it, so pointing it at someone else's server sends your photos there.
Document the current release Eleven pages covering getting a backend running, building from source, what every view does, configuration, the API and WebSocket events, project layout and data model, packaging the executable, self-hosting, the standalone scripts, and troubleshooting. Describes the app as it stands rather than how it got here.
