 Settings, protected Nexus credentials and installation history stay in Electron's per-user app-data directory, outside the depot. Installed setups and recovery folders belong outside the application directory. Do not configure Steam Cloud for credential files. Test updates and uninstall through the actual Steam client to confirm user data and external setups remain intact; local Electron tests cannot establish Steam behavior.

+[Valve's review process](https://partner.steamgames.com/doc/store/review_process) covers the actual store presence and build. Successful packaging or fixture checks do not establish acceptance by Valve. No Steam depot has been uploaded. A partial [real TTW shortcut/launch check](native-steam-acceptance.md) reached the menu after an edition prompt; the revised candidate's direct launch failed before the menu. No gameplay or recording acceptance is claimed. These non-Steam-shortcut checks do not test installing or updating the Loadstone depot through Steam.
 
 Store copy, disclosures, asset production and reviewer handoff are tracked in the [Steam submission draft](steam-submission.md).

 ### Short description
 
-Loadstone brings compatible Bethesda modlists into one Windows library. Import a creator setup, check requirements, install through Wabbajack, and launch its Mod Organizer profile. Games, compatible lists and Nexus access are supplied separately.
+Loadstone brings compatible Bethesda setups into one Windows library. Open a .loadstone recipe, select your owned games and original files, then build and manage a separate Mod Organizer setup. Compatible Wabbajack lists use an optional engine.
 
 ### About this software
 
-Give your modded worlds a home. Loadstone is a Windows desktop tool for installing and managing compatible Bethesda game setups from creator manifests and original Wabbajack archives.
+Give your modded worlds a home. Loadstone is a Windows desktop tool for installing and managing compatible Bethesda game setups. Its documented .loadstone format describes required games, original sources, verified output files and the intended Mod Organizer profile. Loadstone's original source is licensed under GPL-3.0-or-later.
 
-Review a setup's game requirements, source archive and storage needs before installation. Follow installation progress, inspect failures, and keep installed profiles together in your library. Launch through the configured Mod Organizer profile and create desktop or local Steam shortcuts for your setup.
+Review a setup's game requirements, original archives and prepared prerequisites before installation. The native guide builds into a separate folder, shows measured progress and verifies the result before you explicitly add it to your library. Launch through the configured Mod Organizer profile and create desktop or local Steam shortcuts for your setup.
 
-Maintenance controls include declared list updates, retry paths and removal that preserves supported save locations in a recovery folder. Keep your own backups: recovery is not a guarantee that every mod stores saves in a recognized location.
+Resume interrupted native builds after a fresh review. Repair missing or damaged recipe files while retaining replaced originals, or install a different version in a separate folder while preserving the previous playthrough. Reviewed native removal retains profiles, saves, configuration, modified files and untracked content. Keep your own backups: new setup versions may require a new game, and unusual mod save locations require individual review.
 
-You must own and install the required game and DLC and obtain a compatible creator manifest and its original archive. Automated Nexus downloads require an eligible Nexus account with Premium access and a locally entered API key. The installation engine is downloaded separately. Availability depends on the list's original download sources.
+You must own and install the required games and DLC and obtain a compatible recipe and its declared original files. TTW requires both Fallout: New Vegas and Fallout 3. Native local-only recipes need no Nexus connection or Wabbajack engine. For declared Nexus files, choose guided browser downloads with local hash verification or automatic downloads with eligible Premium access and a locally protected API key. Browser sign-in and downloading remain user actions. 7z/RAR extraction requires a separately supplied trusted tool; availability depends on the original download sources.
+
+Compatible Wabbajack setups use a separate creator manifest and the original Wabbajack archive, with an optional upstream engine downloaded independently. Wabbajack files, MO2 installations and Nexus collections are not interchangeable .loadstone packages.
 
 Loadstone does not include Bethesda games or a playable mod collection. The bundled demonstration catalog is illustrative. Compatibility is specific to each creator setup; a Wabbajack archive alone is not a promise of complete game preparation. Some lists require additional steps documented by their authors.

 The current portable build is a local preview, not a Steam depot acceptance result. Record the exact candidate source commit, artifact hashes, depot build ID, test machine and outcomes in a release-specific acceptance report. Valve reviews the store presence and build; local tests do not replace that review. See [Valve review process](https://partner.steamgames.com/doc/store/review_process).
