 The client and rate counter therefore need to be clustered since they communicate on the event bus.

+## How to run stuff:
 
 (Run everything from the parent directory of this directory).
 
 Run the rate counter in a console (give it a unique cluster port)
 
-vertx run org.vertx.java.examples.perf.RateCounter -cp classes -cluster -cluster-port 25501
+`vertx run org.vertx.java.examples.perf.RateCounter -cp classes -cluster -cluster-port 25501`
 
 Run the server in another console (give it 8 instances to utilise the cores on the server)
 
-vertx run org.vertx.java.examples.httpperf.PerfServer -cp classes -instances 8
+`vertx run org.vertx.java.examples.httpperf.PerfServer -cp classes -instances 8`
 
 Run the client in another console:
 
-vertx run org.vertx.java.examples.httpperf.PerfClient -cp classes -instances 8 -cluster -cluster-port 25502
+`vertx run org.vertx.java.examples.httpperf.PerfClient -cp classes -instances 8 -cluster -cluster-port 25502`
 
 Of course, you can run client and server on different machines. You'll probably need a fast network to avoid getting IO bound.
 
 To compare it with the equivalent node.js server, instead of running the vert.x server run the node.js server as follows:
 
-node nodejs-server.js
+`node nodejs-server.js`
 
 and compare the performance.
 
 You can run a clustered node.js too:
 
-node nodejs-cluster-server.js
+`node nodejs-cluster-server.js`
 
 Also.. you can run a vert.x JavaScript server instead of a Java one if you like:
 
-vertx run vertx-server.js -instances 8
+`vertx run vertx-server.js -instances 8`
 
 or the Ruby server:
 
-vertx run vertx_server.rb -instances 8
+`vertx run vertx_server.rb -instances 8`
+
+or the Groovy server:
+
+`vertx run vertx_server.groovy -instances 8`
