# Theme
In the **Theme** section, users can customize the appearance of their ChatNGO interface by switching between different themes or following the system settings for appearance. Here is how you can modify these settings:
**1. Access Theme Settings**
* Click on your profile icon located in the bottom left of the platform.
* From the drop-down menu, click **Theme**.
**2. Choose Your Theme**
You have three theme options to choose from:
* **System**: The platform will automatically follow your device’s default light or dark theme settings.
* **Light**: The interface will be displayed in light mode, providing a brighter appearance.
* **Dark**: The interface will be displayed in dark mode, reducing eye strain and providing a more muted, darker look.
**3. Selecting a Theme**
* Simply click on the desired theme option (System, Light, or Dark) to activate it immediately.
Once you select the preferred theme, your interface will automatically update to reflect the changes. There is no need to save manually—the theme changes are instant.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.chat.ngo/profile/theme.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
