+## Tests
+Defining the tests here...
+
+## Technology
+Kubescape based on OPA engine: https://github.com/open-policy-agent/opa and ARMO's posture controls. 
+
+The tools retrieves Kubernetes objects from the API server and runs a set of [regos snippets](https://www.openpolicyagent.org/docs/latest/policy-language/) developed by (ARMO)[https://www.armosec.io/]. 
+
+The results by default printed in a pretty "console friendly" manner, but they can be retrieved in JSON format for further processing.
