+import { Context, EventHandler } from 'rich-domain';
+
+
+class OrderCreatedEvent extends EventHandler<Order> {
+
+    constructor() {
+        super({ eventName: 'OrderCreated' });
+    }
+
+    dispatch(order: Order): void {

 ```ts
 
-order.addEvent('OTHER_EVENT', (...args) => {
+order.addEvent('Event', (...args) => {
     console.log(args);
 });
 
 // Or add an EventHandler instance
-order.addEvent(new GenerateInvoiceEvent());

+#### How to subscribe to a global event
+
+```ts
+
+import { Context } from 'rich-domain';
+
+const context = Context.events();
+
+context.subscribe('Context:Event', (event) => {
+   const [model] = event.detail;
+   console.log(model);
+});
+
+// dispatch an event to a context with args
+context.dispatchEvent('Context:Event', { name: 'Jane' });
+
+// Dispatching events to specific contexts
+// Dispatches the SIGNUP event to Context-X
+context.dispatchEvent('Context-X:Signup'); 
+
+// Dispatches the SIGNUP event to all contexts
+context.dispatchEvent('*:Signup'); 
+
+// Dispatches all events to all contexts. Not recommended
+context.dispatchEvent('*:*'); 
+
+// Dispatches all events under Context-Y
+context.dispatchEvent('Context-Y:*'); 
+
+```
