# Configuration

docsify supports two ways to configure. 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.
