## Installation
Install the component:
```sh
npm i @vaadin/accordion
```
Once installed, import the component in your application:
```js
import '@vaadin/accordion';
```
## 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/accordion/vaadin-accordion.js) of the package uses the Lumo theme.
To use the Material theme, import the component from the `theme/material` folder:
```js
import '@vaadin/accordion/theme/material/vaadin-accordion.js';
```
You can also import the Lumo version of the component explicitly:
```js
import '@vaadin/accordion/theme/lumo/vaadin-accordion.js';
```
Finally, you can import the un-themed component from the `src` folder to get a minimal starting point:
```js
import '@vaadin/accordion/src/vaadin-accordion.js';
```
