# 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                                                                                |
| --------------------------- | ------------------------------------------------------------------------------------- |
| **Portal Administrator**    | Full access to all administration features for the platform                           |
| **Global Administrator**    | Same as Portal Administrator, with access across all access URLs in a multi-URL 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                        |

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 see the standard Chamilo home page, but with an additional **Administration** link in the sidebar.
