## Installation

Install the component:

```sh
npm i @vaadin/upload
```

Once installed, import the component in your application:

```js
import '@vaadin/upload';
```

## Themes

Vaadin components come with two built-in [themes](https://vaadin.com/docs/latest/styling), Lumo and Material.
The [main entrypoint](https://github.com/vaadin/web-components/blob/main/packages/upload/vaadin-upload.js) of the package uses the Lumo theme.

To use the Material theme, import the component from the `theme/material` folder:

```js
import '@vaadin/upload/theme/material/vaadin-upload.js';
```

You can also import the Lumo version of the component explicitly:

```js
import '@vaadin/upload/theme/lumo/vaadin-upload.js';
```

Finally, you can import the un-themed component from the `src` folder to get a minimal starting point:

```js
import '@vaadin/upload/src/vaadin-upload.js';
```
