+<Description>
+How to work with controlled vs. uncontrolled state in Reka UI.
+</Description>
+
+Reka UI provides flexible state management for components, allowing developers to use either **controlled** or **uncontrolled** state. Understanding when to use each approach ensures better integration with Vue's reactivity system.
+
+---
+
+## Controlled vs. Uncontrolled State
+
+### Controlled State
+A **controlled** component receives its state as a prop and requires explicit updates via event listeners. The parent component manages and synchronizes the state.
+
+#### Example: Controlled `SwitchRoot`
+
+```vue
+<script setup>
+import { ref } from 'vue'
+import { SwitchRoot, SwitchThumb } from 'reka-ui'
+
+const isActive = ref(false)
+
+function handleUpdate(value) {
+  isActive.value = value
+}
+</script>
+
+<template>
+  <SwitchRoot :model-value="isActive" @update:model-value="handleUpdate">
+    <SwitchThumb />
+  </SwitchRoot>
+</template>
+```
+
+**How it works:**
+- The `SwitchRoot` component’s state is managed by the `isActive` ref.
+- The `@update:modelValue` event ensures updates propagate correctly.
+
+<Callout type="tip" title="Use controlled state when:">
+
+- You need to sync state with Vuex, Pinia, or an API.
+- Multiple components rely on the same state.
+- You want fine-grained control over updates.
+
+</Callout>
+
+#### Using v-model with Controlled Components
+
+Vue’s `v-model` syntax provides a convenient way to bind values to controlled components in Reka UI. It automatically handles passing the value and listening for updates.
+
+Example: Using `v-model` with `SwitchRoot`
+
+```vue
+<script setup>
+import { ref } from 'vue'
+import { SwitchRoot, SwitchThumb } from 'reka-ui'
+
+const isActive = ref(false)
+</script>
+
+<template>
+  <SwitchRoot v-model="isActive">
+    <SwitchThumb />
+  </SwitchRoot>
+</template>
+```
+
+### Uncontrolled State
+An **uncontrolled** component manages its own state internally, without requiring a parent-controlled prop. Instead of `modelValue`, Reka UI components use `defaultValue` to initialize state.
+
+#### Example: Uncontrolled `SwitchRoot`
+```vue
+<template>
+  <SwitchRoot default-value="true">
+    <SwitchThumb />
+  </SwitchRoot>
+</template>
+```
+
+**How it works:**
+- The `SwitchRoot` initializes its state with `defaultValue`.
+- State changes occur internally without external control.
+
+<Callout type="tip" title="Use uncontrolled state when:">
+
+- The component does not need to sync with external logic.
+- You want a simpler setup without explicit state management.
+- The state is local and does not impact other components.
+
+</Callout>
+
+## Common Mistakes & Fixes
+
+### 1. Forgetting `@update:checked`
+
+```vue
+<!-- ❌ Incorrect: -->
+<SwitchRoot :modelValue="isActive" />
+
+<!-- ✅ Correct: -->
+<SwitchRoot :modelValue="isActive" @update:modelValue="(val) => isActive = val" />
+```
+
+### 2. Using `modelValue` Instead of `defaultValue`
+
+```vue
+<!-- ❌ Incorrect: -->
+<SwitchRoot :modelValue="true" />
+
+<!-- ✅ Correct: -->
+<SwitchRoot defaultValue="true" />
+```
+
+### 3. Not Providing a Setter for Computed Props
+
+```ts
+// ❌ Incorrect:
+const isActive = computed(() => store.state.toggleState)
+
+// ✅ Correct:
+const isActive = computed({
+  get: () => store.state.toggleState,
+  set: val => store.commit('setToggleState', val)
+})
+```
