# Environment Settings: Branding, AI and Import

Company-wide settings under Manage: logo and colours, rebuilding the knowledge search index, and cleaning up old import versions.

The page **Manage** holds settings that apply to your whole company: your logo and colours, the AI settings for Minerva's knowledge, and the clean-up of old import versions. This page explains each.

> **Permissions:** Customer admins; the section **AI settings** also with feature **Context**: **Edit**. See [Create and Edit Roles](https://docs.noreja.com/en/article/create-and-edit-roles).

### Open the Settings

Open **Settings** (the gear icon) and choose **Manage** under **Environment**; see [Navigating Noreja](https://docs.noreja.com/en/article/navigating-noreja). Customer admins see all three sections. Users whose role has **Context** with **Edit** see only **AI settings**.

![The page Manage: Branding with Company Logo (Desktop Logo, Mobile Logo, Select file, The image may be no larger than 1 MB.), Primary Color, Other Colors and Reset colors; AI settings with Revectorize all context; Graph storage importer settings with Cleanup Neo4j](https://cdn-assets.productfruits.com/e46ab12f-f73c-4280-9293-e8c1ad33bbb9)

### Branding

-   **Company Logo**: upload a **Desktop Logo** (wide) and a **Mobile Logo** (narrow) with **Select file**, up to 1 MB each. The logo is saved right away and replaces the Noreja logo in the top bar. A logo can be replaced, not removed.
-   **Primary Color**: pick your main colour; Noreja derives the matching shades from it. Under **Other Colors** you can adjust these shades one by one.
-   **Reset colors** goes back to Noreja's colours.

Changes are saved automatically and apply to everyone in your company. Presentations and documents that Minerva creates use your logo and colours as well; see [What Minerva Can Do](https://docs.noreja.com/en/article/what-minerva-can-do).

### AI settings

**Revectorize all context** rebuilds the search index of all knowledge in the Context Hub (see [Context Hub: Knowledge for Minerva](https://docs.noreja.com/en/article/contextualizing-knowledge-for-minerva-ai)); documents are processed again completely. It's only needed when Noreja asks you to, for example after a change of the AI model used for the search. It runs in the background, can take a long time for many documents, and causes AI costs. Noreja doesn't ask for confirmation and shows no progress.

### Graph storage importer settings

When an entity or a perspective is imported again, Noreja keeps the previous version as an archive until it's cleaned up. **Cleanup Neo4j** deletes these previous versions now; the current data isn't affected. Noreja does this automatically every night, so you only need it to free space immediately. While an import is running, the clean-up is skipped. It can't be undone. How imports and their versions work is described in [Import Entities and Perspectives: Status and Errors](https://docs.noreja.com/en/article/import-entities-and-perspectives-status-and-errors).
