**[mdast][]** utility to parse markdown.

## Install

[npm][]:

```sh
npm install mdast-util-from-markdown
```

## Use

Say we have the following markdown file, `example.md`:

```markdown
## Hello, *World*!
```

And our script, `example.js`, looks as follows:

```js
var fs = require('fs')
var fromMarkdown = require('mdast-util-from-markdown')

var doc = fs.readFileSync('example.md')

var tree = fromMarkdown(doc)

console.log(tree)
```

Now, running `node example` yields (positional info removed for brevity):

```js
{
  type: 'root',
  children: [
    {
      type: 'heading',
      depth: 2,
      children: [
        {type: 'text', value: 'Hello, '},
        {
          type: 'emphasis',
          children: [{type: 'text', value: 'World'}]
        },
        {type: 'text', value: '!'}
      ]
    }
  ]
}
```

## API

### `fromMarkdown(doc[, encoding][, options])`

Parse markdown to a **[mdast][]** tree.

##### Parameters

###### `doc`

Value to parse (`string` or [`Buffer`][buffer]).

###### `encoding`

[Character encoding][encoding] to understand `doc` as when it’s a
[`Buffer`][buffer] (`string`, default: `'utf8'`).

###### `options.extensions`

Array of syntax extensions (`Array.<MicromarkSyntaxExtension>`, default: `[]`).
Passed to [`micromark` as `extensions`][micromark-extensions].

###### `options.mdastExtensions`

Array of mdast extensions (`Array.<MdastExtension>`, default: `[]`).

##### Returns

[`Root`][root].

## Security

As Markdown is sometimes used for HTML, and improper use of HTML can open you up
to a [cross-site scripting (XSS)][xss] attack, use of `mdast-util-from-markdown`
can also be unsafe.
When going to HTML, use this utility in combination with
[`hast-util-sanitize`][sanitize] to make the tree safe.
