 This folder contains a sample configuration for Huly Kubernetes deployment.
 
+## Requires
+
+Requires a working kubernetes cluster with min one node. Each node should have min 2 vCPUs and 4GB of RAM.
+
+if you don't have any k8s cluster, consider to use [kind setup](KIND.md).
+
 ## Check and update configuration
 
 Huly deployment configuration is located in [config.yaml](config/config.yaml) and [secret.yaml](config/secret.yaml) files.
