[Parser][] for [**unified**][unified].
Parses Markdown to [**mdast**][mdast] syntax trees.
Built on [`micromark`][micromark] and
[`mdast-util-from-markdown`][from-markdown].
Used in the [**remark** processor][remark] but can be used on its own as well.
Can be [extended][extend] to change how Markdown is parsed.
## Install
[npm][]:
```sh
npm install remark-parse
```
## Use
```js
var unified = require('unified')
var createStream = require('unified-stream')
var markdown = require('remark-parse')
var remark2rehype = require('remark-rehype')
var html = require('rehype-stringify')
var processor = unified().use(markdown).use(remark2rehype).use(html)
process.stdin.pipe(createStream(processor)).pipe(process.stdout)
```
[See **unified** for more examples »][unified]
## API
[See **unified** for API docs »][unified]
### `processor().use(parse)`
Configure the `processor` to read Markdown as input and process
[**mdast**][mdast] syntax trees.
## Extending the parser
See [`micromark`][micromark] and [`mdast-util-from-markdown`][from-markdown].
Then create a wrapper plugin such as [`remark-gfm`][gfm].
## 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 remark can also be unsafe.
When going to HTML, use remark in combination with the [**rehype**][rehype]
ecosystem, and use [`rehype-sanitize`][sanitize] to make the tree safe.
Use of remark plugins could also open you up to other attacks.
Carefully assess each plugin and the risks involved in using them.
## Contribute
See [`contributing.md`][contributing] in [`remarkjs/.github`][health] for ways
to get started.
See [`support.md`][support] for ways to get help.
Ideas for new plugins and tools can be posted in [`remarkjs/ideas`][ideas].
A curated list of awesome remark resources can be found in [**awesome
remark**][awesome].
