+# moonlight-vrr-bin - Nonary's fork of Moonlight (https://github.com/Nonary/moonlight-qt),
+# the GameStream client for PCs, with smooth VRR frame pacing (C++ + Qt6).
+#
+# Upstream publishes an AppImage per release, which the PKGBUILD unpacks and
+# installs into /opt, so there is no build step here. GitHub lists each
+# asset's sha256, so a new version needs no download. Upstream builds the
+# AppImage without Wayland support, it runs through XWayland.
+#
+# Version handling is the same as in moonlight-vrr: tags look like
+# v6.1.0-vrr18, pkgver has an underscore for the hyphen, and /releases/latest
+# skips the betas.
