+### One-time Initialization with Effect
+
+View extensions support one-time initialization through the `effect` method. This method is called automatically during setup, but only once per provider class. It's useful for:
+
+- Initializing global state
+- Registering lit elements
+- Setting up shared resources
+
+```typescript
+class MyViewProvider extends ViewExtensionProvider {
+  override effect() {
+    // This will only run once, even if multiple instances are created
+    initializeGlobalState();
+    registerLitElements();
+    setupGlobalEventListeners();
+  }
+}
+```
+
 ### Available View Scopes
 
 The view extension system supports the following scopes:
