## Simple and Intuitive API

Get started with just a few lines of code. Stateless components
make it easy to build complex UIs.

```rs
Button::new("ok")
    .primary()
    .label("Click Me")
    .on_click(|_, _, _| println!("Button clicked!"))
```

## Install GPUI Component

Add the following to your `Cargo.toml`:

```toml-vue
gpui = "{{ GPUI_VERSION }}"
gpui-component = "{{ VERSION }}"
```

## Hello World

The following `src/main.rs` is a simple "Hello, World!" application:

```rs
use gpui::*;
use gpui_component::{button::*, *};

pub struct HelloWorld;
impl Render for HelloWorld {
    fn render(&mut self, _: &mut Window, _: &mut Context<Self>) -> impl IntoElement {
        div()
            .v_flex()
            .gap_2()
            .size_full()
            .items_center()
            .justify_center()
            .child("Hello, World!")
            .child(
                Button::new("ok")
                    .primary()
                    .label("Let's Go!")
                    .on_click(|_, _, _| println!("Clicked!")),
            )
    }
}

fn main() {
    let app = Application::new();

    app.run(move |cx| {
        // This must be called before using any GPUI Component features.
        gpui_component::init(cx);

        cx.spawn(async move |cx| {
            cx.open_window(WindowOptions::default(), |window, cx| {
                let view = cx.new(|_| HelloWorld);
                // This first level on the window, should be a Root.
                cx.new(|cx| Root::new(view, window, cx))
            })?;

            Ok::<_, anyhow::Error>(())
        })
        .detach();
    });
}
```

Run the program with the following command:

```sh
$ cargo run
```
