+Think WhatsApp, but for your microservices architecture. It allows your services to securely talk to each other in **private, shielded channels** without having to expose anything to the outside world. This allows the use of **reactive programming across your entire stack**.
+
+### Server side
+
+every universe has a server that manages messages.  
+Think Kafka, but without Kafka.
+
+```typescript
+import * as smartuniverse from '@pushrocks/smartuniverse';
+
+const myUniverse = new smartuniverse.Universe({
+  messageExpiryInMilliseconds: 60000 // the standard time in milliseconds until a message expires
+});
+

+myUniverse.addChannel('awesomeChannel', 'awesomeChannelPass');
+myUniverse.addChannel('awesomeChannel2', 'jhkjhfsdf87eerkjslkfja9');
+
+myUniverse.start(8765); // start the server and provide the port on which to listen on
+```
+
+### Client side
+
+All your microservices represents clients in the universe that may talk to each other using the universe server.
