-####Limitation
+#### Limitation
 1. Current deployment is http only, to enable https you need to either add another layer of proxy or modify the nginx.cm.yaml to enable https and include a correct certificate
 2. Current deployment does not include Clair and Notary, which are supported in docker-compose deployment.  They will be supported in near future, stay tuned.
