+# Chit Chat
+
+This is a tiny little chat program, that shells out to 'say' to have
+your computer convert to text to audio for you.
+
+You can subscribe to all users in the topic exchange or specific users.
+Queues are created using the name of the user logged in.
+
+In order to use this, one person will have to act as the RabbitMQ host.
+
+You will need to either export an environment variable to specify the
+environment variable with each of the below commands.
+
+```bash
+$ export RABBIT_HOST=<servername>
+```
+
+To start the listener.
+
+This will listen to all users on the exchange.
+
+```bash
+λ ruby lib/6-chit-chat/subscribe.rb 
+ [*] Waiting for gossip from ["#"]. To exit press CTRL+C
+```
+
+You can specify specific routing keys to only listen to specific users.
+
+```bash
+λ ruby lib/6-chit-chat/subscribe.rb mo joe
+ [*] Waiting for gossip from ["mo", "joe"]. To exit press CTRL+C
+```
+
+To start participating in the conversation you can start the REPL.
+
+```bash
+λ ruby lib/6-chit-chat/publish.rb
+> 
+```
+
+Type your message and hit enter to publish the message to all connected
+subscribers.
