# Cover

The Publication cover is a native Ghost feature used to represent your site visually. By default, it is used as the Open Graph image when your site is shared on social media. In this theme, it is also displayed in the [subscribe section](/docs/wind/customization/homepage/subscribe.md).

### Step-by-step:

{% stepper %}
{% step %}
Go to the "**Design & branding**" settings in Ghost Admin and click "**Customize**".
{% endstep %}

{% step %}
Under "**Publication cover**", click "**Upload cover**" and select your file.
{% endstep %}

{% step %}
Click "**Save**" to apply the changes.
{% endstep %}
{% endstepper %}

### Custom Image for Social Media

You can upload a different image for social sharing instead of using the publication cover.

#### Step-by-step:

{% stepper %}
{% step %}
Go to the "**General**" settings in Ghost Admin and open "**Meta data**".
{% endstep %}

{% step %}
Under the "**X card**" or "**Facebook card**" section, upload a custom image.
{% endstep %}
{% endstepper %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://pinathemes.gitbook.io/docs/wind/customization/cover.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
