+### 🎨 Icon Rendering Customization
+
+The `IconRenderProperties` class allows you to customize how your tray icon is rendered. This is an optional parameter when using the Tray component, with a default value already provided:
+
+```kotlin
+iconRenderProperties = IconRenderProperties.forCurrentOperatingSystem()
+```
+
+#### Available Factory Methods:
+
+1. **forCurrentOperatingSystem()**: Creates properties optimized for the current operating system:
+   - Windows: 32x32 pixels
+   - macOS: 44x44 pixels
+   - Linux: 24x24 pixels
+
+   ```kotlin
+   IconRenderProperties.forCurrentOperatingSystem(
+       sceneWidth = 192,    // Optional: Width of the compose scene (default: 192)
+       sceneHeight = 192,   // Optional: Height of the compose scene (default: 192)
+       density = Density(2f) // Optional: Density for the compose scene (default: 2f)
+   )
+   ```
+
+2. **withoutScalingAndAliasing()**: Creates properties that don't force icon scaling and aliasing:
+
+   ```kotlin
+   IconRenderProperties.withoutScalingAndAliasing(
+       sceneWidth = 192,    // Optional: Width of the compose scene (default: 192)
+       sceneHeight = 192,   // Optional: Height of the compose scene (default: 192)
+       density = Density(2f) // Optional: Density for the compose scene (default: 2f)
+   )
+   ```
+
+This allows you to fine-tune how your icon appears in the system tray across different platforms.
+
 ### 🔄 Single Instance Management
 
 The `SingleInstanceManager` ensures that only one instance of the application is running at a time. When a second instance tries to start, it sends a restore request to the existing instance to bring it to the foreground.
