# How to add a base layer to your document

## How to add a document base layer

Adding a base layer to your document will give you a helpful guide for building your story.

Simply upload the base layer (saved in JPEG or PNG ) to your document before you begin building your story. To precisely position elements on the base layer, make sure you match the base image width to the grid width you're working in. For example, if you're designing the desktop breakpoint with 1366px grid width, make sure your base layer image is sized 1366px wide as well. Turn on and off the visibility of the base layer using the toggle button on the right side panel.

Note : You can only upload one base layer document per story at a time, so the same image will be applied for all breakpoints. You can, however, replace the desktop base layer with one sized for tablet and mobile as you work on those breakpoints.

## 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://docs.maker.co/maker-pages/advanced-features/how-to-add-a-base-layer-to-your-document.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.
