This allows for easier customization of it (think of it like `ThreadPoolExecutor` that can be extended and customized). To make this possible we extracted the whole IO handling / multiplexing to another class that is injected into the `MultiThreadIoEventLoopGroup`. 
 
 For example:
-```
+
+```java
 new EpollEventLoop();
 ```
 
 becomes
-```
-new MultiThreadIoEventLoopGroup(EpollIoHandler.newFactory();
 
+```java
+new MultiThreadIoEventLoopGroup(EpollIoHandler.newFactory();
 ```

 Other transports follow the same pattern.
 
 `MultiThreadIoEventLoopGroup` and `SingleThreadIoEventLoop` provide various methods that can be overridden by the user and so provide the ability to:
