+# PWA Icons / Images 
+
+We suggest you to create a svg or png icon (if it is a png icon, with the maximum resolution possible) for your application and use it to generate a favicon package in [Favicon Generator](https://realfavicongenerator.net/).
+
+Once generated, download the ZIP and use android-* icons for pwa-*:
+
+- use `android-chrome-192x192.png` for `pwa-192x192.png`
+- use `android-chrome-512x512.png` for `pwa-512x512.png`
+- `apple-touch-icon.png` is `apple-touch-icon.png`
+- `favicon.ico` is `favicon.ico`
