 Reloader can watch changes in `ConfigMap` and `Secret` and do rolling upgrades on Pods with their associated `DeploymentConfigs`, `Deployments`, `Daemonsets` and `Statefulsets`.
 
+## Compatibility
+
+Reloader is compatible with kubernetes >= 1.9
+
 ## How to use Reloader
 
 For a `Deployment` called `foo` have a `ConfigMap` called `foo-configmap` or `Secret` called `foo-secret` or both. Then add your annotation (by default `reloader.stakater.com/auto`) to main metadata of your `Deployment`
@@ -29,12 +33,46 @@ metadata:

 This will discover deployments/daemonsets/statefulset automatically where `foo-configmap` or `foo-secret` is being used either via environment variable or from volume mount. And it will perform rolling upgrade on related pods when `foo-configmap` or `foo-secret`are updated.
 
+You can restrict this discovery to only `ConfigMap` or `Secret` objects that
+are tagged with a special annotation. To take advantage of that, annotate
+your deployment/daemonset/statefulset like this:
+
+```yaml
+kind: Deployment
+metadata:
+  annotations:
+    reloader.stakater.com/search: "true"
+spec:
+  template:
+```
+
+and Reloader will trigger the rolling upgrade upon modification of any
+`ConfigMap` or `Secret` annotated like this:
+
+```yaml
+kind: ConfigMap
+metadata:
+  annotations:
+    reloader.stakater.com/match: "true"
+data:
+  key: value
+```
+
+provided the secret/configmap is being used in an environment variable or a
+volume mount.
+
+Please note that `reloader.stakater.com/search` and
+`reloader.stakater.com/auto` do not work together. If you have the
+`reloader.stakater.com/auto: "true"` annotation on your deployment, then it
+will always restart upon a change in configmaps or secrets it uses, regardless
+of whether they have the `reloader.stakater.com/match: "true"` annotation or
+not.
+
 We can also specify a specific configmap or secret which would trigger rolling upgrade only upon change in our specified configmap or secret, this way, it will not trigger rolling upgrade upon changes in all configmaps or secrets used in a deployment, daemonset or statefulset.
 To do this either set the auto annotation to `"false"` (`reloader.stakater.com/auto: "false"`) or remove it altogether, and use annotations mentioned [here](#Configmap) or [here](#Secret)

 ### NOTES
+
 - Reloader also supports [sealed-secrets](https://github.com/bitnami-labs/sealed-secrets). [Here](docs/Reloader-with-Sealed-Secrets.md) are the steps to use sealed-secrets with reloader.
 - `reloader.stakater.com/auto: "true"` will only reload the pod, if the configmap or secret is used (as a volume mount or as an env) in `DeploymentConfigs/Deployment/Daemonsets/Statefulsets`
 - `secret.reloader.stakater.com/reload` or `configmap.reloader.stakater.com/reload` annotation will reload the pod upon changes in specified configmap or secret, irrespective of the usage of configmap or secret.
 - you may override the auto annotation with the `--auto-annotation` flag
+- you may override the search annotation with the `--auto-search-annotation` flag
+  and the match annotation with the `--search-match-annotation` flag
