# Getting Started

This section introduces the Chamilo 2.0 administration interface and helps you get oriented.

## Who Is an Administrator?

Chamilo has several levels of administrative roles:

| Role                        | Access                                                                                                                                |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| **Administrator**           | Full access to all administration features for the platform. Also known as **Portal Administrator**                                   |
| **Global Administrator**    | Same as Portal Administrator, with access across all access URLs in a multi-URL (multi-tenant) setup                                  |
| **Sessions Administrator**  | Can manage sessions, enroll users in sessions, and access session-related settings                                                    |
| **Human Resources Manager** | Can view learner progress and tracking data for assigned users                                                                        |
| **Questions Manager**       | Less of an administrator than a content curator, question managers have access to a global question bank to review questions' quality |

This guide focuses primarily on the **Portal Administrator** role, which has the broadest access.

## Logging In

Administrators log in through the same login page as all other users. After entering your credentials, you will be sent (in the absence of other configuration) to the **Administration** page. A notable difference from other user roles is the **Administration** section in the sidebar (not visible to other roles).
