+# PWA Icons Guide
+
+For optimal PWA support, you should add multiple icon sizes. Place these in `app/static/images/`:
+
+## Required Icons:
+- `icon-72x72.png` (72x72)
+- `icon-96x96.png` (96x96)
+- `icon-128x128.png` (128x128)
+- `icon-144x144.png` (144x144)
+- `icon-152x152.png` (152x152)
+- `icon-192x192.png` (192x192)
+- `icon-384x384.png` (384x384)
+- `icon-512x512.png` (512x512)
+
+## Generate Icons:
+You can use your existing `fina-logo.png` and resize it to create these icons.
+
+Using ImageMagick:
+```bash
+cd app/static/images/
+for size in 72 96 128 144 152 192 384 512; do
+  convert fina-logo.png -resize ${size}x${size} icon-${size}x${size}.png
+done
+```
+
+Or use online tools like:

+
+## Update manifest.json
+After creating the icons, update the manifest.json icons array with all sizes.
