 ##### Caution
 This guide assumes you will be using a regular domain name like `diffgram.com`. If you are using an auto generated domain name it may require different configuration.
+SSL is up to you/your IT team. For debugging the config tools like [SSL Labs](https://www.ssllabs.com/ssltest/analyze.html) may be useful.
 
 ##### Guide
 1. If you want to have TLS connections, please make sure you have a domain available and access to the name servers so you can modify the records to point to the IP addresses of the ingress.
