+### Machine-specific Hyprland config
+
+`~/.config/hypr/hyprland/` holds the shared defaults, don't edit them.
+To tweak a single machine (monitors, devices, keybinds…), copy the matching template in `~/.config/hypr/custom/`:
+
+```
+cd ~/.config/hypr/custom
+cp monitors.example monitors.lua
+```
+
+`custom/*.lua` files are ignored by git and loaded after the defaults; missing ones are simply skipped.
+
+Per-app window rules are shared in `custom/windowrules/<app>.lua`. Enable the ones you want in your `custom/windowrules.lua`:
+
+```lua
+require("custom/windowrules/godot")
+```
