### Markdown
It's also possible to write presentations using [Markdown](#markdown).
It's possible to write your slides using Markdown. To enable Markdown, add the `data-markdown` attribute to your `<section>` elements and wrap the contents in a `<textarea data-template>` like the example below. You'll also need to add the `plugin/markdown/marked.js` and `plugin/markdown/markdown.js` scripts (in that order) to your HTML file. _Note: both these dependencies are already included in the default `index.html`._
### Initialization
This is based on [data-markdown](https://gist.github.com/1343518) from [Paul Irish](https://github.com/paulirish) modified to use [marked](https://github.com/chjj/marked) to support [GitHub Flavored Markdown](https://help.github.com/articles/github-flavored-markdown). Sensitive to indentation (avoid mixing tabs and spaces) and line breaks (avoid consecutive breaks).
```html
<section data-markdown>
<textarea data-template>
## Page title
A paragraph with some text and a [link](http://hakim.se).
</textarea>
</section>
If you only have a single presentation on the page we recommend initializing reveal.js using the singleton API.
```js
Reveal.initialize({ keyboard: true });
```
#### External Markdown
You can write your content as a separate file and have reveal.js load it at runtime. Note the separator arguments which determine how slides are delimited in the external file: the `data-separator` attribute defines a regular expression for horizontal slides (defaults to `^\r?\n---\r?\n$`, a newline-bounded horizontal rule) and `data-separator-vertical` defines vertical slides (disabled by default). The `data-separator-notes` attribute is a regular expression for specifying the beginning of the current slide's speaker notes (defaults to `notes?:`, so it will match both "note:" and "notes:"). The `data-charset` attribute is optional and specifies which charset to use when loading the external file.
When used locally, this feature requires that reveal.js [runs from a local web server](#full-setup). The following example customises all available options:
```html
<section data-markdown="example.md"
data-separator="^\n\n\n"
data-separator-vertical="^\n\n"
data-separator-notes="^Note:"
data-charset="iso-8859-15">
<!--
Note that Windows uses `\r\n` instead of `\n` as its linefeed character.
For a regex that supports all operating systems, use `\r?\n` instead of `\n`.
-->
</section>
The `initialize` method returns a promise which will resolve as soon as the presentation is ready and can be interacted with via the API.
```js
Reveal.initialize.then( () => {
// reveal.js is ready
} )
```
#### Element Attributes
Special syntax (through HTML comments) is available for adding attributes to Markdown elements. This is useful for fragments, amongst other things.
If you want to run multiple presentations side-by-side on the same page you can create instances of the Reveal class. Note that you will also need to set the `embedded` config option to true.
```html
<section data-markdown>
<script type="text/template">
- Item 1 <!-- .element: class="fragment" data-fragment-index="2" -->
- Item 2 <!-- .element: class="fragment" data-fragment-index="1" -->
<div class="reveal deck-1">...</div>
<div class="reveal deck-2">...</div>
<script type="module">
import Reveal from 'js/reveal.js';
let deck1 = new Reveal( document.querySelector( 'deck-1' ), { embedded: true } );
let deck2 = new Reveal( document.querySelector( 'deck-2' ), { embedded: true } );
deck1.initialize();
deck2.initialize();
</script>
</section>
```
#### Slide Attributes
Special syntax (through HTML comments) is available for adding attributes to the slide `<section>` elements generated by your Markdown.
```html
<section data-markdown>
<script type="text/template">
<!-- .slide: data-background="#ff0000" -->
Markdown content
</script>
</section>
```
#### Configuring *marked*
We use [marked](https://github.com/chjj/marked) to parse Markdown. To customise marked's rendering, you can pass in options when [configuring Reveal](#configuration):
```javascript
Reveal.initialize({
// Options which are passed into marked
// See https://marked.js.org/#/USING_ADVANCED.md#options
markdown: {
smartypants: true
}
});
