+## Animation Configuration
+
+The library uses React Native Reanimated's `withSpring` for animations. Here are the available configuration options:
+
+### Animation Config
+
+- `stiffness`: Controls how "springy" the animation is (default: 100)
+- `overshootClamping`: Prevents the animation from overshooting its target (default: false)
+- `restDisplacementThreshold`: The minimum displacement from the target to consider the animation complete (default: 0.001)
+- `restSpeedThreshold`: The minimum speed to consider the animation complete (default: 0.001)
+
+### Animation Style
+
+- `scale`: Scale factor for the icon when active (default: 1.2)
+- `rotate`: Rotation in degrees for the icon when active (default: 0)
+- `opacity`: Opacity value for the icon when active (default: 1)
+
+Example:
+
+```typescript
+animationConfig: {
+  stiffness: 100,
+  overshootClamping: false,
+  restDisplacementThreshold: 0.001,
+  restSpeedThreshold: 0.001,
+},
+animationStyle: {
+  scale: 1.2,
+  rotate: 360,
+  opacity: 0.8,
+}
+```
