Pierre Kisters aa9ca183f1 docs: README as overview + options, one docs page per feature
README keeps intro, feature list linking docs/, install, two sessions,
usage, the complete options table, changes outside Nix, rollback,
uninstall. Each feature's details (problem, what you get, configuration,
limitations, how it works) move to its own page in docs/; docs/dashboard.md
is split per feature and docs/changes-outside-nix.md becomes
docs/cleanup.md.

# Cleanup and installer
How `steam-frame-nix-cleanup` and `install.sh` work. What steam-frame-nix
writes outside the Nix store, how to remove it, rollback and uninstall:
[README, Changes outside Nix](../README.md#changes-outside-nix-exceptions),
[Rollback](../README.md#rollback), [Uninstall](../README.md#uninstall).
## Cleanup
`steam-frame-nix-cleanup` (`steamFrame.cleanup.package`, module `cleanup`,
imported by every module) is `install.sh cleanup`, so the same code runs
with Nix (on every switch: `cleanup --orphans --keep <what the configuration
still uses>`) and without it, from the script (bash, coreutils, findutils,
jq, all in SteamOS' `/usr/bin`). Home Manager's `uninstall = true;` runs
`cleanup --all` from the activation. `--quiet` prints only actions,
deferrals and warnings.
It removes an artifact only when it is proven to be its own; anything else
is reported as "left alone" and never touched:
| Artifact | Proof / rule |
|---|---|
| `debugger`: `VRWebHelper.DebuggerEnabled` in `steamvr.vrsettings` | `~/.local/state/steam-frame-nix/steamvr-debugger.armed` holds the value before (older versions: the empty marker `steamvr-debugger`, value before = absent). Restored once SteamVR is stopped; while it runs the runtime drop-in restores it when SteamVR stops. Also the runtime drop-in and restore script themselves. |
| `icons`: `hicolor/scalable/apps/<name>.svg` | links to Breeze in the store, listed in `~/.local/state/steam-frame-nix/icon-fallbacks` (the icon-fallbacks script of 2026-09) |
| `firefox`: `user.js` in Firefox profiles | links to `/app/etc/firefox/steam-frame-nix-desktop-user.js` (left alone while the profile is in use), older links to `*-firefox-*user.js` and copies starting with the steam-frame-nix marker comment, and the values they left in `prefs.js` (only with Firefox closed) |
| `jellyfin` | the hwdec shim entries in the Jellyfin Flatpak's user override `~/.local/share/flatpak/overrides/org.jellyfin.JellyfinDesktop` (nix-flatpak), an empty override file, and the shim copy of earlier versions in `~/.var/app/org.jellyfin.JellyfinDesktop` (marker `~/.local/state/steam-frame-nix/jellyfin-hwdec-shim`) |
| `ui-state`: `~/.local/state/steam-frame-nix/ui-patches/<name>.json` | the dashboard patches' saved choices; `--all` only, never `--orphans`; stray `*.json.tmp` files |
| `dirs` | `~/.local/state/steam-frame-nix` and `/run/user/1000/steam-frame-nix` when empty |
### Left by older versions
Of the rows above, only older versions wrote: the icon fallback links and
their list, the debugger marker `steamvr-debugger`, Firefox `user.js` copies
and links and their `prefs.js` values, the Jellyfin hwdec override entries
(and an empty override file) and the old shim copy.
## Installer
What `install.sh install` sets up is listed in the README under
[Set up by install.sh](../README.md#set-up-by-installsh). The installer runs
`systemctl --user` against the outer session's user manager (the nested
desktop can't reach it with its own environment) and uses the installed
`home-manager` if there is one, else Home Manager's `master`.
