-# EventBus
+# EventBus
+Simple Java EventBus.
+
+Follow steps to start using EventBus (see example in `test -> com.jdotsoft.eventbus.demo.EventBusDemo`):
+- Create `BlueEvent` class which extends base class `Event`.
+This class might have constructor with arguments, member variables, and any methods.
+
+    public class BlueEvent extends Event {
+    }
+- Create `BlueEventListener` interface which extends base interface `EventListener` with method `onBlue(BlueEvent e)`.
+This interface might have any methods declarations, however, only method which returns `void` with single argument `BlueEvent` will be invoked. 
+
+    public interface BlueEventListener extends EventListener {
+       void onBlue(BlueEvent event);
+    }
+- Implement `BlueEventListener` (and other event listeners if required) in some class which will receive the `BlueEvent` event and register it:
+
+    public class BluePanel extends JPanel implements BlueEventListener {
+      public BluePanel() {
+        EventBus.getInstance().registerListeners(this);
+      }
+      @Override
+      public void onBlue(BlueEvent event) {
+        . . .
+      }
+    }
+- Fire event
+
+    eventBus.fire(new BlueEvent());
+    - or -
+    EventBus.getInstance().fire(new BlueEvent());
+
+- Object `BluePanel` will receive event in listener `BlueEventListener` implementation `onBlue(BlueEvent e)`.
+
+
+`EventBus` object could be instantiated as `EventBus eventBus = new EventBus();` somewhere in a main class and passed to listeners.
+Use static `EventBus.getInstance();` as an alternative.
