 This example overlay builds on the previous example and demonstrates how to change
 the namespace that the operator installs into. In this example, the operator installs

-This overlay updates the base configuration by setting the `MAX_CONCURRENT_RECONCILES` environment variable in the operator's Deployment. It enables multiple workers to reconcile the RuntimeComponent custom resource instances concurrently. There are `8` workers set by default, and this setting can be customized in the `overlays/set-max-concurrent-reconciles/operator.properties` file.
