+### Allowing usage of EventRecorder on the Controller
+To raise an event, you must have access to `record.EventRecorder` in the Controller.  Therefore, firstly let's update the controller implementation: 
+```go
+import (
+	...
+	"k8s.io/client-go/tools/record"
+	...
+)
+// MyKindReconciler reconciles a MyKind object
+type MyKindReconciler struct {
+	client.Client
+	Scheme   *runtime.Scheme
+	// See that we added the following code to allow us to pass the record.EventRecorder 
+	Recorder record.EventRecorder
+}
+
+
+### Passing the EventRecorder to the Controller
+Events are published from a Controller using an [EventRecorder]`type CorrelatorOptions struct`,
+which can be created for a Controller by calling `GetRecorder(name string)` on a Manager. See that we will change the implementation scaffolded in `cmd/main.go`:
+```go
+	if err = (&controller.MyKindReconciler{
+		Client:   mgr.GetClient(),
+		Scheme:   mgr.GetScheme(),
+		// Note that we added the following line: 
+		Recorder: mgr.GetEventRecorderFor("mykind-controller"),
+	}).SetupWithManager(mgr); err != nil {
+		setupLog.Error(err, "unable to create controller", "controller", "MyKind")
+		os.Exit(1)
+	}
+```
 
 ### Granting the required permissions
 You must also grant the RBAC rules permissions to allow your project to create Events. Therefore, ensure that you add the [RBAC][rbac-markers] into your controller:
