 ## Quickstart
 
 The following program is a small example of Fluent Logger for Java.
 
-    import java.util.HashMap;
-    import java.util.Map;
-    import org.fluentd.logger.FluentLogger;
-
-    public class Main {
-        private static FluentLogger LOG = FluentLogger.getLogger("app");
-
-        public void doApplicationLogic() {
-            // ...
-            Map<String, Object> data = new HashMap<String, Object>();
-            data.put("from", "userA");
-            data.put("to", "userB");
-            LOG.log("follow", data);
-            // ...
-        }
+```java
+import java.util.HashMap;
+import java.util.Map;
+import org.fluentd.logger.FluentLogger;
+
+public class Main {
+    private static FluentLogger LOG = FluentLogger.getLogger("app");
+
+    public void doApplicationLogic() {
+        // ...
+        Map<String, Object> data = new HashMap<String, Object>();
+        data.put("from", "userA");
+        data.put("to", "userB");
+        LOG.log("follow", data);
+        // ...
     }
+}
+```
 
 To create Fluent Logger instances, users need to invoke getLogger method in 
 FluentLogger class like org.slf4j, org.log4j logging libraries.  The method 
 should be called only once.  By default, the logger assumes fluent daemon is 
 launched locally.  You can also specify remote logger by passing the following 
 options.  
 
-    // for remote fluentd
-    private static FluentLogger LOG = FluentLogger.getLogger("app", "remotehost", port);
+```java
+// for remote fluentd
+private static FluentLogger LOG = FluentLogger.getLogger("app", "remotehost", port);
+```
 
 Then, please create the events like this.  This will send the event to fluentd, 
 with tag 'app.follow' and the attributes 'from' and 'to'.
 
 Close method in FluentLogger class should be called explicitly when application 
 is finished.  The method closes socket connection with the fluentd.
 
-    FluentLogger.close();
+```java
+FluentLogger.close();
+```
