+# Material Weather Icons Sources
+
+This folder contains weather icon assets imported for LanMountainDesktop weather widgets.
+
+The icon packs are included because the product owner explicitly requested original-style assets and accepted the licensing risk for uncertain or non-free icon packs. Keep this notice with the assets.
+
+## Included packs
+
+- `google-weather-v4`: imported from `mbatthew/GoogleWeatherIconsV4Pack`, which documents that the application code is MIT but the weather icons are sourced from Google Weather Icons v4 and have uncertain licensing.
+- `geometric`: imported from `breezy-weather/geometric-icon-provider`, an open-source rewrite of the Geometric Weather icon provider. Breezy's icon-pack index documents related assets as non-free.
+- `breezy`: imported from `breezy-weather/breezy-weather` app resources. Breezy Weather is LGPL-3.0; verify individual asset terms before external redistribution.
+- `lemon-flutter`: imported from `yangSpica27/spica_weather_flutter`, MIT licensed.
+
+## Pending sources
+
+- Lemon Weather v2/v3 are not included yet. They should only be added after a concrete public repository and asset license are verified.
