+## AUR package template (manual)
+
+This folder contains a minimal `PKGBUILD` template for a future AUR package:
+
+- `deskify-bin` (prebuilt GitHub Releases binary)
+
+Notes:
+
+- `sha256sums` are currently set to `SKIP` and should be replaced with real checksums before publishing to AUR.
+- Update `_tag` and `pkgver` when you publish a new release tag.
+
+Local build test:
+
+```bash
+cd packaging
+makepkg -sf
+```
+
