 ## Overview
 
-This example shows how to writing the [Elektron WebSocket API](https://developers.refinitiv.com/elektron/websocket-api) application to subscribe Machine Readable News (MRN) from Thomson Reuters Enterprise Platform (TREP). The example just connects to TREP via a WebSocket connection, then subscribes and display MRN News data in a console or classic Jupyter Notebook. The project are implemented with Python language for both console and Jupyter Notebook applications, but the main concept for consuming and assembling MRN News messages are the same for all technologies.
