 ## Usage
 
+**WARNING**: A bug in the current version is limiting secrets to use the "opaque" type. If you need to use another secret type (eg: `kubernetes.io/dockerconfigjson`), please use kubeseal from release 0.5.1 until [#86](https://github.com/bitnami-labs/sealed-secrets/issues/86) and [#92](https://github.com/bitnami-labs/sealed-secrets/issues/92) are resolved.

 ```sh
 # Create a json/yaml-encoded Secret somehow:
 # (note use of `--dry-run` - this is just a local file!)
