+- Sources like `ExternalSecret`, `SealedSecret`, or `Certificate` from `cert-manager` can create or manage Kubernetes `Secrets` — but they can also be created manually or delivered through GitOps workflows.
 - `Secrets` and `ConfigMaps` are watched by Reloader.
 - When changes are detected, Reloader automatically triggers a rollout of the associated workloads, ensuring your app always runs with the latest configuration.
