 P2P Producer
 ============
 
-Produced by GoldenPogácsa Inc.
+This repository contains the Producer part of the project. The module manages the list of consumers and
+sends data to the currently active one. If that becomes unavailable, it chooses an other one to the data to.
 
-TODO
+Implementation is done in python, the code is put into Docker images (as the consumers). To run the full project
+clone the main repository and run
+*docker-compose up.*
