-# Asynchronous DB calculations reading the binary log
+# MyCDC - MySQL change data capture
 
-## Enviroment setup
+Application to run asynchronous operations based on DB changes. It is divided
+into three services:
+
+- RabbitMQ: Service that allows the exchange and queuing of messages between
+applications.
+- Producer: Reads and filters changes from the DB binary log and adds the 
+relevant messages to each RabbitMQ queue.
+- Consumer: Obtains the elements from the queues and performs the necessary
+operations asynchronously.
+
+## Environment setup
 
 Because a bug with MariaDB wich it's fix is pending to be merged into main
 project branch, a *zongji* fork must be cloned into project root directory.
