 ## Configuration
 
-Asset generation is configured in `capacitor-assets.config.json` at the project root.
+`resources/` is this project's canonical asset source. `@capacitor/assets`
+prioritizes a top-level `assets/` directory over `resources/`, so a legacy
+`assets/` directory can prevent these assets from being discovered. Remove that
+directory when it is empty or obsolete.
