+## Reload Strategies
+Reloader supports multiple "reload" strategies for performing rolling upgrades to resources. The following list describes them:
+- **env-vars**: When a tracked `configMap`/`secret` is updated, this strategy attaches a Reloader specific environment variable to any containers 
+  referencing the changed `configMap` or `secret` on the owning resource (e.g., `Deployment`, `StatefulSet`, etc.).
+  This strategy can be specified with the `--reload-strategy=env-vars` argument. Note: This is the default reload strategy.
+- **annotations**: When a tracked `configMap`/`secret` is updated, this strategy attaches a `reloader.stakater.com/last-reloaded-from` pod template annotation
+  on the owning resource (e.g., `Deployment`, `StatefulSet`, etc.). This strategy is useful when using resource syncing tools like ArgoCD, since it will not cause these tools
+  to detect configuration drift after a resource is reloaded. Note: Since the attached pod template annotation only tracks the last reload source, this strategy will reload any tracked resource should its 
+  `configMap` or `secret` be deleted and recreated.
+  This strategy can be specified with the `--reload-strategy=annotations` argument.

+* When applications are deployed for the first time, Reloader will perform a rolling update of the associated workload. 
+* If you are running Reloader in HA mode all workloads will have a rolling update performed when a new leader is elected. 
+
+If ReloadOnCreate is set to false: 
+* Updates to configMaps/Secrets that occur while there is no leader will not be picked up by the new leader until a subsequent update of the configmap/secret occurs. In the worst case the window in which there can be no leader is 15s as this is the LeaseDuration.
