# Configuration

**docsify** supports two different ways of configuration. You can configure the `window.$docsify` or write configuration on the script tag via `data-*` attributes.

```html
<!-- by $docsify -->
<script>
  window.$docsify = {
    repo: 'QingWei-Li/docsify',
    maxLevel: 3,
    coverpage: true
  }
</script>

<!-- or data-* -->
<script
  src="//unpkg.com/docsify"
  data-repo="QingWei-Li/docsify"
  data-max-level="3"
  data-coverpage>
</script>
```

Both ways are compatible. However, the first way is recommended. It is clear and can be configured in a separate file.

!> In `window.$docsfiy`, the options should be written by camelCase.

## el

- Type: `String`

window.$docsify = {
  el: '#app'
}
```

## repo

- Type: `String`
- Default: `null`

Configure the repository url or a string of `username/repo` can add the [GitHub Corner](http://tholman.com/github-corners/) widget in the top right corner of the site.

```js
window.$docsify = {
  loadSidebar: true,

}

## This is test

<script>
  console.log(2333)

## format-updated
We can display the file update date through **{docsify-updated<span>}</span>** variable. And format it by `formatUpdated`. 
See https://github.com/lukeed/tinydate#patterns
```js
window.$docsify = {
  formatUpdated: '{MM}/{DD} {HH}:{mm}',

  formatUpdated: function (time) {
    // ...

    return time
  }
}
```

## external-link-target

Currently it defaults to _blank, would be nice if configurable:

```js
window.$docsify = {
  externalLinkTarget: '_self' // default: '_blank'
}
```
