+## App Name Configuration
+
+# 1. Set APP_NAME in your .env file
+# 2. Run the script
+./scripts/set_app_name.sh
+
+To make this easier, you can use the provided script that reads `APP_NAME` from `.env` and automatically updates all platform files:
+
+```bash
+# Make sure APP_NAME is set in your .env file first
+./scripts/set_app_name.sh
+```
+
+This script will:
+1. Read `APP_NAME` from your `.env` file
+2. Update `android/app/src/main/AndroidManifest.xml`
+3. Update `macos/Runner/Configs/AppInfo.xcconfig`
+
+**Manual Setup:** If you prefer to set it manually, just update the files listed above directly.
+
+## App Icon Configuration
+
+App icons are platform-specific and must be placed in the correct directories with the correct formats.
+
+### Android Icons
+
+**Location:** `android/app/src/main/res/mipmap-*/`
+
+**Format:** PNG files
+
+**Required Sizes:**
+- `mipmap-mdpi/ic_launcher.png` - 48x48 px
+- `mipmap-hdpi/ic_launcher.png` - 72x72 px
+- `mipmap-xhdpi/ic_launcher.png` - 96x96 px
+- `mipmap-xxhdpi/ic_launcher.png` - 144x144 px
+- `mipmap-xxxhdpi/ic_launcher.png` - 192x192 px
+
+**Instructions:**
+1. Create your app icon as a square image (recommended: 1024x1024 px source)
+2. Generate all required sizes using an icon generator tool (e.g., [App Icon Generator](https://www.appicon.co/))
+3. Replace the existing `ic_launcher.png` files in each `mipmap-*` directory
+4. The icon is referenced in `AndroidManifest.xml` as `@mipmap/ic_launcher`
+
+**Best Practices:**
+- Use PNG format (no transparency for launcher icons on some Android versions)
+- Keep icon simple and recognizable at small sizes
+- Follow Material Design guidelines for Android icons
+- Ensure icon works on both light and dark backgrounds
+
+### macOS Icons
+
+**Location:** `macos/Runner/Assets.xcassets/AppIcon.appiconset/`
+
+**Format:** PNG files
+
+**Required Sizes:**
+- `app_icon_16.png` - 16x16 px
+- `app_icon_32.png` - 32x32 px
+- `app_icon_64.png` - 64x64 px
+- `app_icon_128.png` - 128x128 px
+- `app_icon_256.png` - 256x256 px
+- `app_icon_512.png` - 512x512 px
+- `app_icon_1024.png` - 1024x1024 px
+
+**Instructions:**
+1. Create your app icon as a square image (recommended: 1024x1024 px source)
+2. Generate all required sizes
+3. Replace the existing PNG files in `AppIcon.appiconset/` directory
+4. The `Contents.json` file defines which sizes map to which files - update if needed
+
+**Best Practices:**
+- Use PNG format
+- macOS icons can have transparency
+- Follow macOS Human Interface Guidelines
+- Icon should be recognizable at 16x16 size
+
+### iOS Icons (if adding iOS support)
+
+**Location:** `ios/Runner/Assets.xcassets/AppIcon.appiconset/`
+
+**Format:** PNG files (no transparency for some sizes)
+
+**Required Sizes:** iOS requires many sizes. Use Xcode's App Icon set or a tool like [App Icon Generator](https://www.appicon.co/) to generate all required sizes automatically.
+
+**Best Practices:**
+- Use PNG format
+- Some sizes require no transparency (check iOS guidelines)
+- Follow iOS Human Interface Guidelines
+- Generate all sizes from a 1024x1024 px source
+
+### Icon Generation Tools
+
+Recommended tools for generating all required icon sizes:
+- [AppIcon.co](https://www.appicon.co/) - Online tool, supports multiple platforms
+- [IconKitchen](https://icon.kitchen/) - Google's icon generator
+- [MakeAppIcon](https://makeappicon.com/) - Generates all sizes from one image
+- Xcode (for macOS/iOS) - Built-in asset catalog editor
+
+### Quick Setup
+
+1. **Prepare your icon:** Create a 1024x1024 px square PNG image
+2. **Generate sizes:** Use one of the tools above to generate all required sizes
+3. **Replace files:** Copy generated icons to the appropriate directories
+4. **Test:** Run the app and verify icons appear correctly
