+> Trying to ignore **both `configmaps` and `secrets`** will cause an error in Reloader.
 > ✅ **Workaround:** Scale the Reloader deployment to `0` replicas if you want to disable it completely.
 
+**💡 Workload Type Examples:**
+
+```bash
+# Ignore only Jobs
+--ignored-workload-types=jobs
+
+# Ignore only CronJobs
+--ignored-workload-types=cronjobs
+
+# Ignore both (comma-separated)
+--ignored-workload-types=jobs,cronjobs
+```
+
+> **🔧 Use Case:** Ignoring workload types is useful when you don't want certain types of workloads to be automatically reloaded.
