### ES Module
We provide two JavaScript bundles; `/dist/reveal.es5.js` with support for legacy browers and `/dist/reveal.js` which targets modern browsers with ES6 support.
Here's how to import and initialize the ES module version of reveal.js, including the Markdown plugin:
```html
<script type="module">
import Reveal from '/dist/reveal.js';
import markdown from '/plugin/markdown/markdown.js';
Reveal.initialize({
keyboard: true,
plugins: [ markdown() ]
});
</script>
```
### Configuration ### Configuration
At the end of your page you need to initialize reveal by running the following code. Note that all configuration values are optional and will default to the values specified below.
