 ```coffeescript
-# Example in coffee-script
-
-EtcdClient = require 'node-etcd'
-
-c = new EtcdClient
+# Coffee-script examples:
+Etcd = require 'node-etcd'
+c = new Etcd
 
+# Set a value
 c.set "/key", "value", (err, val) ->
 	console.log err, val

+# Set with expiry (time to live)
+c.setTTL "/key", "value", 5, (err, val) ->
+	console.log err, val
+
+# Atomic setting (test and set)
+c.setTest "/key", "new value", "old value", (err, val) ->

+
+# List machines in the etcd cluster
