+### Understanding Init Modes
+
+When creating state parts, you can specify different initialization modes:
+
+- **`'soft'`** - Allows existing state parts to remain (default behavior)
+- **`'mandatory'`** - Fails if there's an existing state part with the same name
+- **`'force'`** - Overwrites any existing state part
+- **`'persistent'`** - Enables WebStore persistence using IndexedDB
+
 ### Defining State Parts
 
 State parts represent separable sections of your state, making it easier to manage and modularize. For example, you may have a state part for user data and another for application settings.

-### Persistent State
+### Additional State Methods
 
-`Smartstate` supports the concept of persistent states, where you can maintain state across sessions. To utilize this, specify a persistent mode when getting a state part:
+`StatePart` provides several useful methods for state management:
 
 ```typescript
-const settingsStatePart = await myAppSmartState.getStatePart<AppStateParts, ISettingsState>(
+// Wait for a specific state condition
+await userStatePart.waitUntilPresent();
+
+// Setup initial state with async operations
+await userStatePart.stateSetup(async (state) => {
+  // Perform async initialization
+  const userData = await fetchUserData();
+  return { ...state, ...userData };
+});
+
+// Batch multiple state changes for cumulative notification
+userStatePart.notifyChangeCumulative(() => {
+  // Multiple state changes here will result in a single notification
+});
+```
+
+### Persistent State with WebStore
+
+`Smartstate` supports persistent states using WebStore (IndexedDB-based storage), allowing you to maintain state across sessions:
+
+```typescript
+const settingsStatePart = await myAppSmartState.getStatePart<ISettingsState>(
   AppStateParts.SettingsState,
   { theme: 'light' }, // Initial state
   'persistent' // Mode
 );
+
+// Initialize the persistent state (required for persistent mode)
+await settingsStatePart.init();
 ```
 
-This mode ensures that the state is saved and can be reloaded even after the application restarts, providing a seamless user experience.
+Persistent state automatically:
+- Saves state changes to IndexedDB
+- Restores state on application restart
+- Manages storage with configurable database and store names
+
+### Performance Optimization
+
+`Smartstate` includes built-in performance optimizations:
+
+- **State Hash Detection**: Uses SHA256 hashing to detect actual state changes, preventing unnecessary notifications when state values haven't truly changed
+- **Cumulative Notifications**: Batch multiple state changes into a single notification using `notifyChangeCumulative()`
+- **Selective Subscriptions**: Use selectors to subscribe only to specific state properties
+
+### RxJS Integration
+
+`Smartstate` leverages RxJS for reactive state management:
+
+```typescript
+// State is exposed as an RxJS Subject
+const stateObservable = userStatePart.select();
+
+// Automatically starts with current state value
+stateObservable.subscribe((state) => {
+  console.log('Current state:', state);
+});
+
+// Use selectors for specific properties
+userStatePart.select(state => state.username)
+  .pipe(
+    distinctUntilChanged(),
+    filter(username => username !== undefined)
+  )
+  .subscribe(username => {
+    console.log('Username changed:', username);
+  });
+```
 
 ### Comprehensive Usage
 
 Putting it all together, `@push.rocks/smartstate` offers a flexible and powerful pattern for managing application state. By modularizing state parts, subscribing to state changes, and controlling state modifications through actions, developers can maintain a clean and scalable architecture. Combining these strategies with persistent states unlocks the full potential for creating dynamic and user-friendly applications.
 
-Remember to leverage TypeScript for its excellent support for types and interfaces, enhancing your development experience with type checking and IntelliSense, ensuring a more reliable and maintainable codebase.
+Key features:
+- **Type-safe state management** with full TypeScript support
+- **Reactive state updates** using RxJS observables
+- **Persistent state** with IndexedDB storage
+- **Performance optimized** with state hash detection
+- **Modular architecture** with separate state parts
+- **Action-based updates** for predictable state modifications
 
 For more complex scenarios, consider combining multiple state parts, creating hierarchical state structures, and integrating with other state management solutions as needed. With `@push.rocks/smartstate`, the possibilities are vast, empowering you to tailor the state management approach to fit the unique requirements of your project.
