+### Angular v20+ Bindings API
+
+Angular Testing Library also supports Angular v20's native bindings API, which provides a more direct way to bind inputs and outputs:
+
+```typescript
+import { render, screen, inputBinding, outputBinding } from '@testing-library/angular';
+import { CounterComponent } from './counter.component';
+
+describe('Counter with Bindings API', () => {
+  it('should render counter using bindings', async () => {
+    await render(CounterComponent, {
+      bindings: [inputBinding('counter', () => 5), inputBinding('greeting', () => 'Hello Bindings!')],
+    });
+
+    expect(screen.getByText('Current Count: 5')).toBeVisible();
+    expect(screen.getByText('Hello Bindings!')).toBeVisible();
+  });
+
+  it('should handle outputs with bindings', async () => {
+    const clickHandler = jest.fn();
+
+    await render(CounterComponent, {
+      bindings: [inputBinding('counter', () => 0), outputBinding('counterChange', clickHandler)],
+    });
+
+    const incrementButton = screen.getByRole('button', { name: '+' });
+    fireEvent.click(incrementButton);
+
+    expect(clickHandler).toHaveBeenCalledWith(1);
+  });
+});
+```
+
+The new bindings API provides several benefits:
+
+- **Native Angular Integration**: Uses Angular's official bindings API
+- **Better Performance**: Bindings are handled natively by Angular
+- **Improved Type Safety**: Leverages Angular's built-in type checking
+
+Both approaches are supported and can be used interchangeably based on your preference and Angular version.
