 # Microservices
 
-A basic example of microservice architecture which demonstrates communication between a few loosely coupled services. This includes messages between a server terminal and a web user interface with a database service in the middle.
+A basic example of microservice architecture which demonstrates communication between a few loosely coupled services.
 
-Written in Go, this mainly showcases the exchange of information using RabbitMQ—between back end services—and WebSocket—between front end and back end.

+* Uses RabbitMQ to communicate between services
-The services are built using Docker which includes a multistage build example. The whole application is served with Docker Compose.
+* Uses WebSocket to talk to the front end
+* Stores data in PostgreSQL
+* Uses React for front end development
+* Builds and runs the application with Docker
