# Set up your brand
Turn your existing brand materials into a theme Decky can use to design presentations
**Choose how you want Decky to build your theme.**
**Build from my existing brand**\
Choose this if your company already has presentations that represent how your decks should look. Add an existing presentation and your company website. Decky uses them to build a theme based on your current presentation style and brand.
**Create or beautify a brand**\
Choose this if you want Decky to create a new presentation style or improve what you have. Add your company website and visual inspiration. Decky uses those inputs to create a theme that fits your brand while giving it more creative freedom.
**Not sure which to choose?**\
If you already have a deck you want future presentations to resemble, choose **Build from my existing brand**. Otherwise, choose **Create or beautify a brand**.
### How to do it
* Open **Themes** and select **New theme**.
* Choose **Build from my existing brand** or **Create or beautify a brand**.
* Add the requested brand materials, website, or inspirtaional images.
* Continue through setup while Decky analyzes your inputs.
* Review the theme Decky creates.
* Make changes to the theme before using it for presentations.
### Tips
* Use current, approved materials rather than older presentations.
* A Theme can include typography, colors, imagery, and writing rules.
* You do not need to recreate every brand rule manually.

## 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://decky.gitbook.io/decky-docs/getting-started/set-up-your-brand.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.
