 ### 📜 Certificates
 
-By default this template will deploy a wildcard certificate with the Let's Encrypt staging servers. This is to prevent you from getting rate-limited on configuration that might not be valid on bootstrap using the production server. Once you have confirmed the certificate is created and valid, make sure to switch to the Let's Encrypt production servers as outlined in the certificate manifest.

 - To view the certificate request run `kubectl -n networking get certificaterequests`
 - To verify the certificate is created run `kubectl -n networking get certificates`
 
-📍 Do not enable the production certificate until you are sure you will keep the cluster up for more than a few hours.
+You should start to see your applications using the new certificate.
