+
+## Navigation Patterns
+
+Different approaches to implementing navigation in your application.
+
+- **[Single Page Navigation](./spa-navigation.md)** - Client-side routing with History API
+- **[Isomorphic Routing](./isomorphic-routing.md)** - Universal routing (server + client)
+- **[Declarative Routing](./declarative-routing.md)** - Custom resolvers for declarative definitions
+
+## Authentication & Authorization
+
+Protecting routes and managing user access.
+
+- **[Authorization](./authorization.md)** - Protected routes and role-based access control
+- **[Redirects](./redirects.md)** - Handling redirects
+
+## Navigation UI
+
+Building navigation components for your application.
+

+Enhancing the navigation experience.
+
+- **[Page Transitions](./page-transitions.md)** - Animated transitions between routes
+
+## Performance
+
+Optimizing your routing setup for better performance.
+
+- **[Code Splitting](./code-splitting.md)** - Lazy loading routes with dynamic imports

+
+## Framework Integration
+
+Integrating Universal Router with popular frameworks and tools.
+
+- **[React & Redux](./react-redux.md)** - Redux-first routing patterns
+- **[Server Methods](./server-methods.md)** - Handling GET/POST/PUT/DELETE on the server
+- **[Hot Module Replacement](./hmr.md)** - Development setup with Vite and Webpack
+
+## Advanced Topics
