## CDN
For fast prototyping, we recommend using [esm.run](https://esm.run/)<!-- {.external} -->,
a CDN that allows you to use `@material/web` without installing and building
from NPM.

For production, follow the [install](#install) and [build](#building) steps
below.
## Install
<!--#include file="../googlers/quick-start-install.md" -->
Install Material web components using
[npm and node](https://nodejs.org)<!-- {.external} -->.
```shell
npm install @material/web
```
## Import
Import element definitions from
`@material/web/<component>/<component-variant>.js`.
```js
// index.js
import '@material/web/button/filled-button.js';
import '@material/web/button/outlined-button.js';
import '@material/web/checkbox/checkbox.js';
```
<!--#include file="../googlers/quick-start-import.md" -->
## Usage
Use the `<component-name>` tag in HTML markup. Refer to the
[component docs](components/) for more guidance on using each component.
[Playground](https://lit.dev/playground/#gist=37d28012c5ec6de30809bdf4a6e26cb6)<!-- {.external} -->
```html
<script type="module" src="./index.js"></script>
<label>
Material 3
<md-checkbox checked></md-checkbox>
</label>
<md-outlined-button>Back</md-outlined-button>
<md-filled-button>Next</md-filled-button>
```
## Building
<!--#include file="../googlers/quick-start-build.md" -->
Material web components uses bare module specifiers that must be resolved with
tools until [import maps](https://github.com/WICG/import-maps)<!-- {.external} --> are
adopted.
We recommend following
[lit.dev's modern build for production](https://lit.dev/docs/tools/production/#modern-only-build)<!-- {.external} -->
for a more in-depth build guide.
### Rollup quick start
For a quick start, we recommend using [Rollup](https://rollupjs.org/)<!-- {.external} -->
to resolve bare module specifiers into a bundled file.
Install Rollup and a plugin to resolve bare module specifiers.
```shell
npm install rollup @rollup/plugin-node-resolve
```
Create a bundle from an entrypoint `index.js` file and use it in a `<script>`
`"src"` attribute.
```shell
npx rollup -p @rollup/plugin-node-resolve index.js -o bundle.js
```
```html
<script src="./bundle.js"></script>
```
