 ## Application Overview
 
-This example shows how to writing an application to contribute your data to RCC using [Websocket API for Pricing Streaming and Real-Time Service ](https://developers.refinitiv.com/en/api-catalog/elektron/refinitiv-websocket-api) (aka WebSocket API) through Refinitiv Real-Time Distribution System (Refinitiv Real-Time Advanced Distribution and Advanced Data Hub servers). The example just connects to Refinitiv Real-Time Advanced Distribution Server via a WebSocket connection, then sends an off-stream post to contribute item to RCC server via that Refinitiv Real-Time Distribution System. The project are implemented with Python language for both console and Jupyter Notebook applications, but the main concept and post message structures are the same for all technologies.

 Developers can contributing data to RCC with Real-Time SDK C++/Java (RSSL connection) and WebSocket API (WebSocket connection). Currently, there are three methods to contribute data to the RCC. 
 
 1. **Use Refinitiv Real-Time SDKs to directly connect to RCC to contribute data.** To use this method, please refer to the following tutorials:

 This article is focusing on **the second method** which is contributing data via Refinitiv Real-Time Distribution System servers (Real-Time Advanced Distribution and Advanced Data Hub servers).  The servers will take care of the RCC connection, JSON-OMM conversion, and login process for the application.
