# XMPP

**XMPP** (Extensible Messaging and Presence Protocol), also known as **Jabber**, is a communication protocol used by the Universität Greifswald for real-time instant messaging.

## Operational Workflow
Based on the URZ documentation (specifically for the [[pidgin]] client), the basic usage workflow is as follows:
- **Starting a Chat**: Double-click a contact (Buddy) in the Buddy-List to open a chat window.
- **Interface**: The chat window consists of a conversation history area (top) and a text input area (bottom).
- **Transmission**: Pressing the **Enter** key sends the composed message.
