+# Machine-Specific Overrides
+
+
+`*.ini` files here are loaded *after* the shared files one level up
+    and may override any of their keys.
+
+Use them for anything tied to one machine's hardware or capabilities,
+    for example, suspend/hibernate bindings, HiDPI scaling, or night light warmth.
+
+Same rules as for the shared files:
+    paths are anchored at the root of `dconf`,
+    and `/home/user` is rewritten before loading.
+
+Two files are *generated* and must not be edited by hand:
+
+- `palette.ini` is written by [`color-palette`](../../../.local/bin/color-palette)
+- `temporary_background.ini` is written by
+  [`randomize-background`](../../../.local/bin/randomize-background)
+  and removed again by
+  [`gnome-restore`](../../../.local/bin/gnome-restore)
+  on the next login
+
+
+
+## Examples
+
+
+Suspend and hibernate bindings are reserved
+    in [`key-bindings.ini`](../key-bindings.ini)
+    but only bound here
+    on machines that support them:
+
+```ini
+# local/power.ini
+
+[org/gnome/settings-daemon/plugins/media-keys]
+
+suspend=['<Super><Alt>Escape']
+hibernate=['<Super><Alt><Shift>Escape']
+```
+
+
+A HiDPI panel:
+
+```ini
+# local/display.ini
+
+[org/gnome/desktop/interface]
+
+text-scaling-factor=1.25
+```
+
+
+A machine in a dim room that should run warmer by default:
+
+```ini
+# local/night-light.ini
+
+[org/gnome/settings-daemon/plugins/color]
+
+night-light-temperature=uint32 1800
+```
