# Customizing Tellius

Customize Tellius by uploading your organization’s logo and selecting a color palette. Super users can update branding for the login page, UI, and overall experience.

To make Tellius more personalized for your organization, you can customize its appearance by adding your own logo and changing the color scheme.

{% hint style="warning" %}
Please note that the customization can only be performed by super users.
{% endhint %}

### **Changing the logo**

Here are the steps to customize your logo and theme in Tellius:

1. In the left panel, click on the user icon in the bottom corner.
2. Select **Settings → Application Settings → Styles**.

3. Under **Square Logo**, click on **Replace** button and choose the required image. Or, click on **Revert to Default logo** to restore the Tellius logo.

{% hint style="info" %}
Upload a **square-sized image** of your logo, preferably in 1:1 aspect ratio for optimal display. The supported file formats are .png, .jpg, .svg and the maximum file size is 5 MB.
{% endhint %}

4. The square logo will be visible in the following areas:

* Home icon (top left corner in the pane)
* In the menu when users click on the user icon in the bottom left corner (near the version number)
* Favicon (icon in the browser tab)

{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://help.tellius.com/6.0/getting-started/admin-guide/customizing-tellius.md?ask=<question>&goal=<user_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.
