# Customization
## Standard texts
You can create standard texts sorted in different groups. Standard texts can be as short as one line and as long as a complete document. You can insert these standard texts in your templates.
## Fields
Standard fields are one or more fields that you often use in your templates. You can place them in a step of your template. A new standard field can be made by clicking on the green 'new field' button or by saving a step/field in your template as standard field.
## Headers / Footers
You can create standard Headers and Footers for your templates. A new Header / Footer design can be created by clicking on the green 'new section' button.
The design won't show up in the template itself but will be shown in the final document. You can drag a text or image field in the header/footer section and design in to your liking.

## 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.fillthedoc.com/fillthedoc-ui.md?ask=&goal=
```
`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.
