+# State Management Documentation
+
+## State Management Solution
+
+The application uses **Zustand** as the primary state management solution for the following reasons:
+
+- Simplified API with minimal boilerplate
+- Strong performance characteristics for complex state
+- Good compatibility with React's concurrent features
+- Excellent TypeScript support
+- Middleware support for additional functionality
+
+## State Structure
+
+The state is divided into several specialized stores for different concerns:
+
+### 1. User Store
+
+Manages authentication state and user profile information.
+
+```javascript
+// userStore.js
+import create from 'zustand';
+import { persist } from 'zustand/middleware';
+
+const useUserStore = create(
+  persist(
+    (set, get) => ({
+      user: null,
+      isAuthenticated: false,
+      credits: 0,
+      isPremium: false,
+      
+      // Actions
+      setUser: (userData) => set({
+        user: userData,
+        isAuthenticated: true,
+        credits: userData.credits,
+        isPremium: userData.isPremium
+      }),
+      
+      logout: () => set({
+        user: null,
+        isAuthenticated: false,
+        credits: 0,
+        isPremium: false
+      }),
