+We want to automatically inject a [keycloak gatekeeper](https://github.com/keycloak/keycloak-gatekeeper) container in a pod, for any deployment that requires to connect
  to keycloak, instead of manually adding a sidecar container with each deployment 
 
 ## Solution
 
-This controller will continuously watch deployments/statefulsets/daemonsets in specific or all namespaces,
- and automatically add a sidecar container for keycloak proxy. Configuration for the keycloak proxy is done through
- annotations of the respective deployment or with ConfigMap of the ProxyInjector.
