+The CloudEvents API got promoted to the CNCF repo:
 
-Simple CDI libray for the link:https://github.com/cloudevents/spec[CloudEvents Specification]
-
-A more detailed introduction is link:./introduction.md[here]
-
-Below is a simple overview!
-
-== JAX-RS and Apache Kafka support
-
-Adding the `jax-rs` or `kafka` module to your application integrates, either the `/ce` JAX-RS endpoint, or a configurable Kafka consumer for handling CloudEvents from within your application!
-
-Receiving different multi-cloud events, using the CDI API:
-
-[source,java]
-----
-public class Monitor {
-
-    public void receiveCloudEventFromAWS(@Observes @EventType(name = "aws.s3.object.created") CloudEvent<?> cloudEvent) {
-
-        System.out.println("S3 event: " + cloudEvent);
-
-    }
-    public void receiveCloudEventFromAzure(@Observes @EventType(name = "Microsoft.Storage.BlobCreated") CloudEvent<?> cloudEvent) {
-
-        System.out.println("Azure event: " + cloudEvent);
-
-    }
-}
-----
-
-== Java SE / Weld-SE support
-
-Vanilla CDI support and APIs for CloudEvents
-
-=== Creating and firing an event:
-
-[source,java]
-----
-public class EventPublisher {
-
-    @Inject
-    private Event<CloudEvent<MyCustomEvent>> cloudEvent;
-
-    public void doAndTrigger() throws Exception {
-
-        // do some domain specific stuff...
-
-        CloudEvent<MyCustomEvent> event = new CloudEventBuilder<MyCustomEvent>()
-                .eventType("Cloud.Storage.Item.Created")
-                .source(new URI("/trigger"))
-                .eventID(UUID.randomUUID().toString())
-                .build();
-
-        cloudEvent.select(
-                    new EventTypeQualifier("Cloud.Storage.Item.Created"))
-                .fire(event);
-
-    }
-}
-----
-
-=== Receiving the event
-
-[source,java]
-----
-...
-    public void receiveCloudEvent(@Observes @EventType(name = "Cloud.Storage.Item.Created") CloudEvent cloudEvent) {
-
-        receiver.ack();
-    }
