+# Slide Hooks
+
+Lifecycle hooks for slide components.
+
+## Available Hooks
+
+```ts
+import { onSlideEnter, onSlideLeave, useIsSlideActive } from '@slidev/client'
+
+const isActive = useIsSlideActive()
+
+onSlideEnter(() => {
+  // Called when slide becomes active
+})
+
+onSlideLeave(() => {
+  // Called when slide becomes inactive
+})
+```
+
+## Important
+
+Do NOT use `onMounted` / `onUnmounted` in slides - component instance persists even when slide is inactive.
+
+Use `onSlideEnter` and `onSlideLeave` instead.
+
+## Use Cases
+
+- Start/stop animations
+- Play/pause media
+- Initialize/cleanup resources
+- Track analytics
