+  without Steam's overlay preload.
+- Update notifications (`notify`, `lib/update-notifier.sh`, top-level,
+  ticked by default, 2.5.0): a user timer (daily, and the service is wanted
+  by `plasma-workspace.target`) runs `patches/steamify-notifier.py`, which
+  compares GitHub's newest release with the `seen` version every run records
+  (`notify_seen` in the entry point, only while it's on, with `frontend`: app or terminal, which Open Steamify starts again, in a `systemd-run --scope` since the check's own unit is stopped when it exits). It must never

 - VRAM booster (`vram`, `lib/vram-booster.sh`, top-level, ticked by
   default, 2.3.0; only available when `/sys/fs/cgroup/dmem.capacity` lists a
-  VRAM region of at least 2 GB; greyed out with an NVIDIA card,
+  `vram`/`vidmem` region (numbered too) of at least 2 GB, whatever the brand;
-  `vram_selectable`, faked with `WIZARD_VRAM_FAKE_NVIDIA=1`): CachyOS's `dmemcg-booster` (system + user service) and
+  greyed out with an NVIDIA card whose driver lists none, `vram_selectable`,
+  faked with `WIZARD_VRAM_FAKE_NVIDIA=1`; `WIZARD_VRAM_CAPACITY=<file>` reads
+  the regions from a copy): CachyOS's `dmemcg-booster` (system + user service) and
   `plasma-foreground-booster`, like SteamOS 3.9's VRAM management. The
   latter only starts with `kcgroupsrc [Foreground Booster] autostart=true`
   (set with `kset`). Disable removes only the packages it installed
   (`state_get vram installed_pkgs`).
+- Install-time mode (`steamify.sh --defaults`, 2.6.0): applies what the menu
+  would preselect, no menu or prompts (needs passwordless sudo). The Steam
+  Machine ISO ([steammachine-cachyos-live-iso](https://github.com/theupriser/steammachine-cachyos-live-iso))
+  runs it in the installer for a user who has never logged in: no session
+  bus, user systemd or plasmashell. So every `systemctl --user` goes through
+  `user_systemctl` (`lib/common.sh`; without a session only unit files change,
+  via `--root=/`), and the theme, when the layout is still `/etc/skel`'s,
+  removes it so Plasma builds Vapor's layout at the first login. What needs
+  that layout (single user's launcher) runs then, from a one-time autostart
+  (`lib/first-login.sh`, `--first-login`) that also opens the app.
+  `--options <id>,...` (exactly these on, the rest off; an item on brings its
+  parent) and `--boot gamescope|desktop` (desktop only with `gaming`) (2.7.0,
+  `defaults_options` in `lib/menu.sh`); the ISO's installer page passes them.
+  Items this PC can't use are left off with a warning, not an error.
+  `steamify.sh --boot gamescope|desktop` on its own (2.7.0, for scripts) only
+  switches `boot` on an installed conversion: `WANTED` is `CURRENT` plus
+  that, so no updates or removals a normal run would pick.
 - `Relogin=true` means a gamescope that fails to start is relaunched in a
   tight loop; keep that in mind when changing session handling.

@@ -236,17 +238,78 @@ Where Steam Machine support was set up before 2.2.0, the menu ticks the
 power-off fix as a new default sub-option (see feature versions below), so a
 normal run adds it.
 
+## Add as non-Steam game
+
+A sub-option of the Steamify shortcut (`steamgame`, `lib/steam-game.sh`, new
+in 2.5.1, ticked along with the shortcut): Steamify CachyOS in every Steam
+account's non-Steam games (`~/.local/share/Steam/userdata/<id>/config/shortcuts.vdf`,
+binary VDF, edited by `patches/steam-shortcuts.py`), starting the shortcut's
+`run-app`, with the icon rendered as PNG (`~/.local/share/steamify/steamify.png`;
+Steam shows no SVG). Why: while Steam runs, a Steam Controller only talks to
+Steam, which gives its input to the game it started (Steam Input); on the
+desktop through its desktop layout (A = Enter, B = Esc, Y = Space, X =
+Steam's keyboard), in gaming mode as a gamepad.
+
+Steam reads the list only at startup and writes it back on exit, so Steam is
+closed (`steam -shutdown`) for the edit and started again (through
+`steam-desktop-autostart.service` when it's there). That's refused in gaming
+mode and when Steamify itself was started from Steam (`SteamGameId`), since
+closing Steam would end it. An entry for the start script that's already
+there (added by hand, or with the path from before 2.5.0) is updated, not
+added twice; what was done is recorded per account (state `steamgame`:
+`<account>=<appid> added|updated`) and a copy of each list is kept in the
+state directory before the first change. Turning it off (or the shortcut)
+removes every entry for the start script, since it can't start anything
+without it.
+
+Started from Steam, the app re-executes itself without Steam's overlay
+(`LD_PRELOAD` of `gameoverlayrenderer.so` makes Qt abort) and
+`steamify-app.sh` keeps it in the foreground (`SteamGameId`), or Steam
+counts the game as ended right away and stops giving it the controller.
+
+## Update notifications
+
+The **Update notifications** option (new in 2.5.0, ticked by default)
+installs `patches/steamify-notifier.py` as
+`~/.local/share/steamify/bin/steamify-notifier` with two user
+units in `~/.config/systemd/user`: `steamify-update-check.timer` (daily,
+`Persistent=`) and `steamify-update-check.service` (also wanted by
+`plasma-workspace.target`, so it checks a minute after each desktop login).
+Nothing stays running while there's no update.
+
+Every Steamify run records its version as `seen` (`notify.state`). The check
+asks GitHub for the newest release; when it's newer than `seen` and not the
+`skipped` version, it shows a notification (`notify-send` with the buttons
+**Open Steamify** and **Skip this version**) and a tray icon (click: open;
+menu: open, skip, remind me later). Closing the notification keeps the
+icon; opening Steamify in any way records the new version and ends it. It
+only runs on the Plasma desktop: gamescope shows no notifications or tray,
+so an update found in gaming mode waits for the next desktop login. It never
+installs anything: the shortcut always starts the newest release, which then
+shows what's new or updated for this install.

 ## VRAM booster
 
 SteamOS 3.9 manages the dGPU's VRAM per cgroup: the game in front is
 protected, background apps are evicted first. Without it a game that needs
 most of the VRAM (8 GB on the Steam Machine) can be pushed into system RAM
 by the desktop and other apps, and stutter. The kernel side is the `dmem`

+## Where Steamify keeps its files
+
+In the home folder, everything is under `steamify`:
+
+| Where | What |
+|---|---|
+| `~/.local/state/steamify/` | State (`*.state`), undo journals (`*.journal`), the saved panel layout (`theme-layout/`) |
+| `~/.local/share/steamify/app/` | The app (`steamify-app.sh` downloads it here) |
+| `~/.local/share/steamify/bin/` | The shortcut's start scripts (`run-app`, `run-wizard`) and `steamify-notifier` |
+| `~/.local/share/icons/hicolor/scalable/apps/steamify.svg` | The shortcut's icon |
+| `~/.local/share/applications/steamify-*.desktop` | The launcher entries |
+| `~/.config/systemd/user/` | `steamify-update-check.*`, `steam-desktop-autostart.service` |
+
+System-wide: `/usr/local/lib/steamify/` (kernel headers script),
+`/usr/src/steamify-*` (DKMS modules), `/var/cache/steamify/kernel` (the old
+kernel pin's packages), and `*.bak-gamescope-wizard` backups next to the
+system files that were edited (that name stays: it's how they're found again).
+
+Before 2.5.0 the home folder paths used the project's old name
+(`cachyos-gamescope-boot`). `migrate_layout` (`lib/state.sh`) moves them at
+every start of a newer version, once, and leaves symlinks under the old names
+so an older release still finds the same state; it fixes the paths in the
+launcher entries and the update check's unit, and merges when both exist.
+The headers script moves when Steam Machine support is set up again.
