 ### Resolver
 
 Here is a simple example showing how to use the resolver:
 
+```ruby
 	Async::Reactor.run do
 		resolver = Async::DNS::Resolver.new([[:udp, "8.8.8.8", 53], [:tcp, "8.8.8.8", 53]])
 
 		addresses = resolver.addresses_for("www.google.com.")
 
 		puts addresses.inspect
 	end
 	=> [#<Resolv::IPv4 202.124.127.240>, #<Resolv::IPv4 202.124.127.216>, #<Resolv::IPv4 202.124.127.223>, #<Resolv::IPv4 202.124.127.227>, #<Resolv::IPv4 202.124.127.234>, #<Resolv::IPv4 202.124.127.230>, #<Resolv::IPv4 202.124.127.208>, #<Resolv::IPv4 202.124.127.249>, #<Resolv::IPv4 202.124.127.219>, #<Resolv::IPv4 202.124.127.218>, #<Resolv::IPv4 202.124.127.212>, #<Resolv::IPv4 202.124.127.241>, #<Resolv::IPv4 202.124.127.238>, #<Resolv::IPv4 202.124.127.245>, #<Resolv::IPv4 202.124.127.251>, #<Resolv::IPv4 202.124.127.229>]
+```
 
 ### Server
 
 Here is a simple example showing how to use the server:
 
+```ruby
 	require 'async/dns'
 	
 	class TestServer < Async::DNS::Server
 		def process(name, resource_class, transaction)
 			@resolver ||= Async::DNS::Resolver.new([[:udp, '8.8.8.8', 53], [:tcp, '8.8.8.8', 53]])
 			
 			transaction.passthrough!(@resolver)
 		end
 	end
 	
-	server = TestServer.new(listen: [[:udp, '127.0.0.1', 2346]])
+	server = TestServer.new([[:udp, '127.0.0.1', 2346]])
 	
 	server.run
+```
 
 Then to test you could use `dig` like so:
 
 	dig @localhost -p 2346 google.com
