 Using the library is very simple, here is an example of publishing a service entry:
 
+```
+package main
+
+import (
+	"github.com/micro/mdns"
+	"os"
+)
+
+func main() {
+
 	// Setup our service export
 	host, _ := os.Hostname()
-    info := []string{"My awesome service"},
+	info := []string{"My awesome service"}
-    service, _ := NewMDNSService(host, "_foobar._tcp", "", "", 8000, nil, info)
+	service, _ := mdns.NewMDNSService(host, "_foobar._tcp", "", "", 8000, nil, info)
 
 	// Create the mDNS server, defer shutdown
 	server, _ := mdns.NewServer(&mdns.Config{Zone: service})
-    defer server.Shutdown()

 Doing a lookup for service providers is also very simple:
 
+```
+package main

+
+func main() {

 	go func() {
 		for entry := range entriesCh {
 			fmt.Printf("Got new entry: %v\n", entry)
