+The easiest drop-in way to start using the metrics recorder is by creating a `SetStatusCondition` wrapper, which 
 comes instead of `meta.SetStatusCondition`.
 
 To delete the metrics for a given custom resource, simply call `RemoveConditionsFor` and pass the object.
 
 ```go
+const (
+    kind = "MyCr"
+)
+
+// SetStatusCondition utility function which replaces and wraps meta.SetStatusCondition calls
+func (r *MyReconciler) SetStatusCondition(cr *v1.MyCR, condition metav1.Condition) bool {

+    if changed {

-You can also use `RecordConditionFor` for more flexible metric recording without updating the custom resource's status
