 ## 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 and . 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.

 *Note:* The news message is in UTF-8 JSON string format. Some news messages that contains special unicode character may not be able to show in Windows OS console (cmd, git bash, powershell, etc) due to the OS limitation. Those messages will be print as ```UnicodeEncodeError exception. Cannot decode unicode character``` message in a console instead.

 *Note:* 
 - The Python example has been qualified with Python versions 3.6.5 and Python 3.7.4 (Docker 19.03.1 - CentOS 7)
 - Please refer to the [pip installation guide page](https://pip.pypa.io/en/stable/installing/) if your environment does not have the [pip tool](https://pypi.org/project/pip/) installed. 
 - If your environment already have a websocket-client library installed, you can use ```pip list``` command to verify a library version, then use ```pip install --upgrade websocket-client``` command to upgrade websocket-client library. 
 - It is not advisable to change the ADH/ADS configuration, if you are not familiar with the configuration procedures. Please consult your Market Data administrator for any questions regarding TREP-MRN service configuration.
-- You can install a classic Jupyter Notebook on your local machine and then test the example on the machine. The alternate choice is a free Jupyter Notebook on cloud environment such as [Azure Notebook](https://notebooks.azure.com/) provided by Microsoft.
