+# Timer Source to Log Sink
+
+This example shows how to create a simple timer `event source` and a log
`event sink`. The timer events emitted are consumed by a simple logging
connector which will print out those events.
+
+## Create events source and sink
+
+Let's start by creating the timer event source and log event sink as
`kamelet`s.
+```
+$ kubectl apply -f timer-source.kamelet.yaml
+$ kubectl apply -f log-sink.kamelet.yaml
+```
+
+You can check the newly created `kamelet`s in the list.
+```
+$ kubectl get kamelets
+
+NAME PHASE
+log-sink Ready
+timer-source Ready
+```
+
+## Create channel destination
+
+Let's continue by creating a `knative` destination.
+```
+$ kubectl apply -f timer-events.yaml
+```
+
+## Binding events
+
+We can now bind the timer event source to produce events on the destination
with the `timer-source.binding.yaml` configuration.
+```
+$ kubectl apply -f timer-source.binding.yaml
+```
+In a similar fashion you can bind to the log sink in order to consume those
events with the `log-sink.binding.yaml` configuration.
+```
+$ kubectl apply -f log-sink.binding.yaml
+```
+You can check the newly created bindings listing the `KameletBidings`.
+```
+$ kubectl get KameletBindings
+
+NAME PHASE
+log-event-sink Ready
+timer-event-source Ready
+```
+
+### Watch the event sink
+
+After a while you will be able to watch the event consumed by the underlying
`log-event-sink` integration:
+
+```
+$ kamel log log-event-sink
+
