Docsy theme hero image

Hello
I am using the Docsy theme and am adding a hero image to the index page. Where do I add the image to index.html? If you can provide an example that would be great. Below is my existing index.html code:

+++

title = “Goldydocs”

linkTitle = “Goldydocs”

+++

{{< blocks/cover title=“Welcome” image_anchor=“top” height=“full” color=“orange” >}}

<a class=“btn btn-lg btn-primary mr-3 mb-4” href=“{{< relref “/docs” >}}”>

{{< /blocks/cover >}}
