# Customizing branding in Atomicwork

You can tailor Atomicwork to reflect your company’s unique brand identity. Customize the name and logo of the platform to align with your corporate branding guidelines, and give Atom a name and avatar your employees will recognize.

## Customize the name and logo

* Go to **Settings > Organization > Branding** in the **Organization tab**.

* In the Accounts tab, enter the name of your organization.

* Click **Upload Logo**.

* Choose your logo file (recommended formats:.png,.jpeg).

* Ensure the logo dimensions are 280x280 pixels or greater for optimal display.

* Click **Update.**

## Customize Atom’s name and avatar

How you change Atom’s name and avatar depends on where your employees talk to Atom.

If your tenant is connected to **Microsoft Teams**, you can do this from within Atomicwork:

* Go to **Settings > Enterprise AI > Configuration > Assistant branding**.

* Enter the name your employees will use to address Atom, and upload an avatar.

* Click **Update.** **Note:** Updating Atom’s name here only updates it in the Atomicwork platform. To personalize Atom in Microsoft Teams for your users, you ***must*** complete the personalization in Microsoft Teams. **[Please read Microsoft Team’s help centre article on app customization to execute this step](https://learn.microsoft.com/en-us/microsoftteams/customize-apps#create-a-default-customization-for-an-app)** .

If your tenant is connected to **Slack**, Atom’s name and icon come from your Slack app manifest instead. See [Set up a custom-branded Slack app for Atom](/documentation/ai-knowledge/atom/setting-up-atom-in-slack).
