## 🚀 Getting Started

### Running Tests
```bash
# Run all TDD tests
cargo test tdd_tests --workspace

# Run tests for specific component
cargo test tdd_tests -p leptos-shadcn-button

# Run with verbose output
cargo test tdd_tests --workspace -- --nocapture
```

### Using Components
```rust
use leptos_shadcn_button::Button;
use leptos_shadcn_card::Card;
use leptos_shadcn_input::Input;

// All components are ready for production use
let button = view! { <Button>"Click me"</Button> };
let card = view! { <Card>"Card content"</Card> };
let input = view! { <Input placeholder="Enter text" /> };
```
