# Customise Image

If our global images don’t meet your requirements, you can customise them, creating a custom image specific to your needs.

Note: This feature is only available to Professional subscriptions. If you are currently on an Essential subscription please upgrade to Professional first. To do this, navigate to the details page of your subscription, click on the dot-menu and on “Upgrade Subscription”.

To customise a global image follow the instructions below:

1. Navigate to the details page of your Professional subscription.
2. Open the tab **Custom Images**.
3. Click on the **(+) Plus** sign on the right side, which will open the wizard.
4. Choose the global image you wish to customise.
5. Enter a **name** and a **description** for the custom image.
6. Click on **Create**.
   1. We will get the image ready, this will take a few minutes. You can see it’s status in the **Custom Images** tab. Once it is in the status **Customising** it is ready for you to make your changes.
7. [Connect to the runner](/products/ci-engine/how-to/enable-debug-mode.md#connect-to-runner) of your custom image.
8. Make your changes to the image. Please have a look at [important information](/products/ci-engine/resources/custom-images.md#important-information) on custom images.

11. Open the tab **Custom Images**.
12. On the image you just finished customising, click on the **(**•••**) More** button.

## 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://doc.flow.swiss/products/ci-engine/how-to/customise-image.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.
