# Changelog widget

1. Install the widget SDK by following the steps described below:

{% content-ref url="/pages/-MkT-mqpZEgkRg32PTEn" %}
[Installing widgets](/widgets/installing-widgets.md)
{% endcontent-ref %}

2. After installing the SDK code you need to add an attribute **data-prodcamp-changelog** to a button that you want to use to open the changelog widget, and after that - call the Changelog init function:

```javascript
<script>
    ProdCamp('initChangelog');
</script>
```

It's recommended to place the script above in a separate \<div> block.
