 To use the library, first add ProtocolLib.jar to your Java build path. Then, add ProtocolLib
 as a dependency (or soft-dependency, if you can live without it) to your plugin.yml file:
 
+````yml
 depends: [ProtocolLib]

 Future versions will be available in a public Maven repository, possibly on Maven central. But it
 will always be possible to reference ProtocolLib manually.
 
 Then get a reference to ProtocolManager in onLoad() and you're good to go.
 
+````java
 private ProtocolManager protocolManager;
 
 public void onLoad() {
     protocolManager = ProtocolLibrary.getProtocolManager();

 It's also possible to read and modify the content of these packets. For instance, you can create a global
 censor by listening for Packet3Chat events:
