-# This patch would need to be applied to fix dependency version issues
-# For now, let's try a different approach - use a snapshot of the repo before the breaking changes
+# This file documents the approach taken to build stremio-linux-shell
+# from master branch with a Rust version compatible with nixpkgs nixos-25.11
+
+# Approach: Create a patched version of Cargo.toml with older dependencies
+# that are compatible with Rust 1.91
+
+# The master branch currently (261f46f) requires:
+# - gtk4 0.11.3 (requires Rust 1.92)
+# - libadwaita 0.9.1 (requires Rust 1.92)
+# - webkit6 0.6.1 (requires Rust 1.92)
+
+# We need to pin these to older versions that work with Rust 1.91:
+# - gtk4 0.11.2 (last version before 1.92 requirement)
+# - libadwaita 0.9.0
+# - webkit6 0.6.0
+
+# However, this requires patching Cargo.toml, which is complex.
+# The cleaner solution is to use nixpkgs-unstable which has Rust 1.94+.
+
+# Currently, the flake.nix overlays use nixpkgs-unstable for stremio-linux-shell
+# which should work, but there are native build dependencies that need to be installed.
+
+# Build dependencies needed for native GTK4 build:
+# - pkg-config (for finding libraries)
+# - glib, cairo, pango, gdk-pixbuf (buildInputs)
+# - wrapGAppsHook4 (for GTK4 wrapping)
+# - nodejs (for server.js)
