+## Check how cloud native your CNFs are
+
+Functest Kubernetes integrates the CNTi Test Catalog which is an open source
+and vendor neutral tool that can be used to validate a telco application's
+adherence to cloud native principles and best practices.
+
+Both cnf_testsuite and cnf_testsuite_workload leverages CoreDNS as the target
+CNF but you're free to validate your own CNFs as the following example.
+
+Download cnf-testsuite.yml and the helm dir to test Envoy
+```bash
+git clone https://github.com/cnti-testcatalog/testsuite.git
+mv testsuite/example-cnfs/envoy .
+rm -rf testsuite
+```
