-:::tip When to Use
-Use this when you need to show UI based on whether a sheet is open, or react to status changes. Separate from `useBottomSheetControl` to avoid unnecessary re-renders in components that only need to trigger sheets.
+:::tip Works with All Sheet Types
+This hook accepts any string ID, so it works with portal sheets, persistent sheets, and inline sheets (using the ID returned from `useBottomSheetManager().open()`).
 :::
 
 ```tsx
+// Portal/persistent sheet
 const { status, isOpen } = useBottomSheetStatus('my-sheet');
+
+// Inline sheet (using ID from open())
+const { open } = useBottomSheetManager();
+const sheetId = open(<MySheet />);
+// ...
+const { status, isOpen } = useBottomSheetStatus(sheetId);

 ### Parameters
 
 | Parameter | Type | Description |

-| `id` | `BottomSheetPortalId` | The sheet ID to observe |

+# Persistent Sheets
+
+Persistent sheets are **pre-mounted** bottom sheets that stay in memory even when closed. They open instantly without mount delay and preserve their internal state between open/close cycles.
+
+## When to Use
+
+- **Frequently accessed sheets** - Scanner, camera, quick actions
+- **State preservation** - Forms, multi-step wizards, media players
+- **Instant open** - When mount delay is noticeable
+
+## Basic Usage
+
+```tsx
+import {
+  BottomSheetPersistent,
+  useBottomSheetControl,
+} from 'react-native-bottom-sheet-stack';
+
+function App() {
+  return (
+    <BottomSheetManagerProvider id="main">
+      <BottomSheetScaleView>
+        <HomeScreen />
+      </BottomSheetScaleView>
+      <BottomSheetHost />
+
+      {/* Persistent sheet - always mounted */}
+      <BottomSheetPersistent id="scanner">
+        <ScannerSheet />
+      </BottomSheetPersistent>
+    </BottomSheetManagerProvider>
+  );
+}
+
+function HomeScreen() {
+  const scanner = useBottomSheetControl('scanner');
+
+  return (
+    <Button
+      title="Open Scanner"
+      onPress={() => scanner.open({ scaleBackground: true })}
+    />
+  );
+}
+```
+
+## State Preservation
+
+Internal component state is preserved between open/close cycles:
+
+```tsx
+const ScannerSheet = forwardRef((props, ref) => {
+  const { close } = useBottomSheetContext();
+  // State is preserved when sheet is closed and reopened
+  const [scanResult, setScanResult] = useState<string | null>(null);
+  const [isScanning, setIsScanning] = useState(false);
+
+  const handleScan = () => {
+    setIsScanning(true);
+    // ... scanning logic
+    setScanResult('QR-ABC123');
+    setIsScanning(false);
+  };
+
+  return (
+    <BottomSheetManaged ref={ref} enableDynamicSizing>
+      <View>
+        {scanResult ? (
+          <Text>Result: {scanResult}</Text>
+        ) : (
+          <Button title="Start Scan" onPress={handleScan} />
+        )}
+        <Button title="Close" onPress={close} />
+      </View>
+    </BottomSheetManaged>
+  );
+});
+```
+
+Close the sheet and reopen it - `scanResult` is still there.
+
+
+## Comparison with Portal API
+
+| Feature | `BottomSheetPortal` | `BottomSheetPersistent` |
+|---------|--------------------|-----------------------|
+| Context preservation | ✅ | ✅ |
+| State preservation | ❌ (remounts) | ✅ |
+| Instant open | ❌ | ✅ |
+| Memory usage | Lower | Higher |
+| Best for | Regular sheets | Frequently used sheets |
+
+## Passing Params
+
+You can pass params when opening:
+
+```tsx
+const scanner = useBottomSheetControl('scanner');
+
+scanner.open({
+  scaleBackground: true,
+  params: { source: 'home', title: 'Scan QR Code' },
+});
+```
+
+Access them in the sheet:
+
+```tsx
+const ScannerSheet = forwardRef((props, ref) => {
+  const { params } = useBottomSheetContext<'scanner'>();
+
+  return (
+    <BottomSheetManaged ref={ref}>
+      <Text>{params?.title ?? 'Scanner'}</Text>
+    </BottomSheetManaged>
+  );
+});
+```
+
+## Type Safety
+
+Register your persistent sheet IDs for type-safe params:
+
+```tsx
+// bottom-sheet.d.ts
+declare module 'react-native-bottom-sheet-stack' {
+  interface BottomSheetPortalRegistry {
+    scanner: { source: 'home' | 'navigation'; title?: string };
+  }
+}
+```
+
+Now `useBottomSheetControl('scanner')` has typed `open()` and `params`.
+
+## Placement
+
+`BottomSheetPersistent` can be placed **anywhere** inside `BottomSheetManagerProvider` - at the app root, on a specific screen, or nested deep in your component tree.
+
+The only requirement: **it must stay mounted** to be accessible. If you unmount it, the sheet won't be available until it mounts again.
+
+```tsx
+// Option 1: At app root - always available
+<BottomSheetManagerProvider id="main">
+  <BottomSheetScaleView>
+    <App />
+  </BottomSheetScaleView>
+  <BottomSheetHost />
+  <BottomSheetPersistent id="scanner">
+    <ScannerSheet />
+  </BottomSheetPersistent>
+</BottomSheetManagerProvider>
+
+// Option 2: On a specific screen - available only when screen is mounted
+function HomeScreen() {
+  return (
+    <View>
+      <BottomSheetPersistent id="quick-actions">
+        <QuickActionsSheet />
+      </BottomSheetPersistent>
+      {/* ... screen content */}
+    </View>
+  );
+}
+```
+
+:::tip
+For sheets that should be accessible from anywhere in your app, place them at the root level to ensure they're always mounted.
